After Doug Jones’s win, here's what Democrats need to do to retake the Senate in 2018

If they hold all their own seats (which won’t be easy), they need to pick up two more.

Just a few months ago, practically no one would have predicted that Democrats would pick up a US Senate seat in the Alabama special election. But they did with Doug Jones’s victory Tuesday — and their chances for retaking the chamber next year have dramatically improved.

It’s long been very difficult to plot a plausible path to a Democratic Senate takeover in 2018, since the party faces such a disadvantage in the map. Democrats have needed to gain, on net, three seats. Assuming they defend all 26 of their own that are up (no easy task), there are then two Republican-held seats — Nevada and Arizona — that have seemed seriously in play.

But the other six Republican seats up next year have long seemed like long shots — meaning it was difficult to envision where Democrats could pick up that elusive third GOP-controlled seat. Not anymore, though — as former Obama administration staffer Matthew Miller tweeted after Jones won, the magic number for the party is now down to two:

Six months ago, I asked the smartest Dem Senate strategist where the three seats to win the majority back were: "Nevada, Arizona, and an act of God." Got the hardest one first.

The Alabama result also serves as a reminder that seemingly uncompetitive races can, under certain circumstances, tighten up. A divisive GOP primary ended in the controversial Moore defeating the party establishment’s preferred candidate. The race was closer than expected even before Moore was accused of sexually assaulting two teenagers last month; after it, Jones got enough of a boost to win.

So it’s a good time to review the entire lineup of Republican Senate seats on the ballot — or that could plausibly be on the ballot — in 2018. We can think of them as follows:

The top two targets: Nevada and Arizona
Two tougher targets: Texas and Tennessee
The possibility that John McCain’s seat in Arizona will also open up
The rest: Wyoming, Nebraska, Utah, and Mississippi (and any other potential special elections)

I’m going to focus on these GOP-held seats, but also just keep in mind that Democrats would also have to play an enormous amount of defense in 2018. Of the 26 of their own seats on the ballot, 10 will be in states Trump won, and five of those will be in states he won overwhelmingly. And for each of their incumbents who does lose, the number of GOP-held seats Democrats would have to win to retake control would go up by one.

The top two targets: Nevada and Arizona

Dean Heller, the most vulnerable GOP incumbent, and Jeff Flake, who’s retiring.

Dean Heller of Nevada has long been the most endangered Republican Senate incumbent, since his is the only GOP-held seat up in a state Trump lost (Hillary Clinton won it by 2.5 points). But things have only gotten worse for him over the course of this year. First, he infuriated conservatives by trying to negotiate changes to the Obamacare repeal bill, and then he infuriated liberals by utterly caving on the issue after reportedly getting an earful from billionaire donors. More recently, he bragged that he “helped write” the deeply unpopular GOP tax bill.

In the general election, Heller will likely face Rep. Jacky Rosen, a Democrat who was first elected to the House of Representatives just last year, but who won the nod of the Democratic establishment in this race. But first he has to get past a primary challenge from Danny Tarkanian, who’s said he’s won the backing of party gadfly Steve Bannon. And though polling of the primary has been sparse so far, Tarkanian has led in some of the ones we’ve seen — signaling a tough road ahead for Heller.

The second obvious target for Democrats is the Arizona seat currently held by Sen. Jeff Flake (R-AZ), who is retiring. Republican leaders hope that Rep. Martha McSally, a retired Air Force colonel, will win the nomination, but she’d face an ugly primary fight against former state Sen. Kelli Ward. Ward is a favorite of some populist conservatives in the state (as well as Bannon), but is viewed by the establishment as a fringe figure who could lose big. Democratic leaders, meanwhile, successfully convinced their preferred candidate — Rep. Kyrsten Sinema (D-AZ) — to run, and she’s the favorite to win the nomination.

To reiterate: If Democrats manage to hold all of their own seats (something that, again, will be quite difficult!), and win just these two GOP-held seats, they’ll end up with a 51-49 Senate majority in 2019.

Two tougher targets: Texas and Tennessee

Moving on to Republican seats that are much more of a reach for Democrats — but maybe not completely safe for the GOP — there’s Ted Cruz’s seat in Texas, and the seat of retiring Sen. Bob Corker in Tennessee.

For years, Democrats have been dreaming of making serious gains in Texas — and for years, they’ve failed to do so, despite the growth in the state’s Hispanic population. In 2016, though, Donald Trump only won the state by 9 points, the worst performance for a GOP presidential nominee there in decades. And the senator up for reelection in 2018 is Ted Cruz, a controversial figure with many enemies, who currently has a weak approval rating.

This time around, Democrats have a charismatic and energetic challenger for Cruz in Rep. Beto O’Rourke (a former punk rocker who my colleague Jeff Stein interviewed earlier this year). O’Rourke very definitely an underdog — Texas is a conservative state, it’s an expensive state to compete in, Cruz is a formidable fundraiser, and O’Rourke is still little-known. Still, if the fired-up Democratic enthusiasm we’ve seen this year holds up, this race might end up being closer than many expect.

Next, there is the Tennessee seat currently held by Sen. Bob Corker (R), who is retiring. Donald Trump won Tennessee by a whopping 26 points, so this race is definitely a stretch for Democrats. But former Gov. Phil Bredesen (D) has decided to jump into the race — and though he hasn’t run for office since 2006 and could be a bit rusty, he has won statewide before. The likely GOP nominee is Rep. Marsha Blackburn, a staunch conservative.

Then, John McCain is not in good health

It may be impolite to discuss it, but Sen. John McCain (R-AZ) has brain cancer and, he says, a “poor prognosis.” If McCain should pass away or decide to step down in the coming months, his seat would be temporarily filled by an appointee from Arizona’s Republican governor, and a special election to fill the remaining four years of McCain’s term would be scheduled at the same time as the 2018 midterms.

If this were to happen, Arizona would suddenly have both of its US Senate seats on the ballot next year — giving Democrats another pickup opportunity in a state Trump won by just 3.5 points.

Some of the possible Democratic candidates in that scenario would likely be people who considered running for Flake’s seat but ended up declining — like Phoenix Mayor Greg Stanton or former Rep. Ann Kirkpatrick (both of whom are currently running for congressional seats), or State Rep. Randall Friese (a trauma surgeon who treated former Rep. Gabby Giffords after her shooting).

As for Republicans, depending on the timing of the vacancy, likely primary rivals Kelli Ward and Martha McSally could end up running in different races after all. Arizona has several other ambitious Republican members of Congress and state politicians too. For now, though, McCain remains in the Senate and has expressed no plans to step down.

The rest

The other remaining GOP-held Senate seats are in such deeply conservative states that few would give Democrats more than an infinitesimal chance of winning any of them. Still, Doug Jones did just pull off his longest-of-shots upset, so let’s run through the remaining possibilities on the table:

Utah: There’s some intrigue around this seat, as 83-year-old Sen. Orrin Hatch (R) has been viewed as likely to retire but hasn’t confirmed his plans to do so just yet. If he does retire, former presidential candidate Mitt Romney will likely run for the GOP nomination. In either case, Salt Lake County Council member Jenny Wilson is running for the Democratic nod.
Wyoming: Sen. John Barrasso (R-WY), who’s close to Mitch McConnell and serves on the GOP Senate leadership team, is running again. Bannon and his allies have mused about recruiting a wealthy conservative — like investor Foster Friess or Blackwater founder Erik Prince — to challenge him in the primary. For Democrats, Jackson Hole businessman Gary Trauner announced last week that he’ll run.
Nebraska: Sen. Deb Fischer (R-NE) will be up for reelection. A conservative in a conservative state, Fischer has nevertheless had a difficult time adapting to the age of Trump — she called on him to leave the race last October after the Access Hollywood “grab ’em by the pussy” tape was released, but then said a few days later that she’d vote for him anyway. Businesswoman and Lincoln City Council member Jane Raybould is running for the Democratic nomination there.
Mississippi: The genial, leadership-aligned Sen. Roger Wicker (R-MS) might face a conservative primary challenge from Chris McDaniel (who nearly won a contentious Senate primary in the state in 2014). It’s not yet clear who the strongest Democratic candidate would be here.
Another special: Finally, it’s of course possible that another unexpected special election could be added to the lineup. For instance, Sen. Thad Cochran (R-MS) has been in poor health, and there have been reports that President Trump might nominate Sen. Tom Cotton (R-AR) to head the CIA.

Both Mississippi and Arkansas are such conservative states, as are the others mentioned here. But again ... Doug Jones did win.

We have a request

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of issues with relying on ads and subscriptions to keep the lights on:

1. Advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan.

2. We’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — we believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

It’s important that we have several ways we make money, and that’s why we ask readers for help keeping Vox free. Our goal today is for 47 Vox readers to pledge an annual financial gift to Vox to help us keep our work free for everyone. Will you become one of them?
