There are still lots of people running for president. By the end of this election cycle, at least 20 different candidates — and possibly more — will have appeared onstage during a nationally televised debate. Even politicos can have trouble matching all those names to all those faces. The Republican debates had moments that felt like a hellish, anonymous game of ping-pong: two unidentified white dudes attacking each other mercilessly. Will tonight's Democratic debate be any less baffling to you? Well...
You might have thought you were safe — after all, you know what Hillary Clinton and Bernie Sanders look like. But what about the other Democrats running very quiet (or unsuccessfully loud) presidential campaigns: former Maryland Gov. Martin O'Malley, former Virginia Sen. Jim Webb, and former Rhode Island Gov. Lincoln Chafee? Can you miss the face of Harvard professor and Democratic candidate Lawrence Lessig (who didn't qualify for tonight's debate) if you don't know what that face looks like?
You can learn about all of the Democratic candidates in our debate preview. But if you really want to be ahead of the curve before tonight's debate, we've got you covered. Above, we mixed up pictures of the four Democratic presidential candidates not named Clinton or Sanders with pictures of four of the more anonymous-looking Republicans. (No one said we were making this easy.)
Test yourself; test other people; use them as flashcards if you want to cram. You may not be able to talk at length about the policy differences between Lincoln Chafee and Jim Webb, but at least you'll know which one is which.
