"It's never too late," Portillo said. "As old as I am, I keep fighting. How could anyone not vote?"
Portillo came from Mexico in the 1980s and became a US citizen in 2013. She voted for the first time in the US this summer during state primaries. "I was so emotional," she said. "It was a feeling I had never felt before."
Portillo said her top issue this election is immigration reform. But she said she's also been studying up on local issues before she heads to the ballot box.
"This is why I vote," Portillo said, "because it's one more voice."
