One person Clinton doesn't have to convince is a Phoenix man who has taken a unique approach to supporting her candidacy for President.
It's more than a campaign sign or bumper sticker.
He's the first person in Arizona to get a "Hillary 16" license plate. He got it a year ago and gets a reaction everywhere he goes.
Whenever Marc Chatow goes in his car, he gets attention.
What type of reaction does he get?
"That's a good question, it's been a mixed bag, I've had people give me a thumbs up, thumbs down, but now that she is officially running, I think I'm going to be seeing more reaction on both sides," said Marc Chatow.
His license plate definitely gets a lot of looks.
"I actually got this license plate a year ago, and I just wanted to be ahead of the game," said Chatow.
Some people get bumper stickers or signs to show their support, so why a license plate?
"I just did the license plate; I think it's a bit more classier than a bumper sticker that would fader over the months, it just looks better," he said.
Chatow says Clinton's beliefs align with his own, and he's willing to pay the $25 annual fee for the plate, in hopes of spreading the message one car he passes at a time.
"I just wanted to let people in Arizona know that I'm for Hillary, and now that she's officially running I don't regret it one bit, and I'm proud to be a supporter," said Chatow.
Marc said he's been hearing from other Clinton supporters around the country who say they'd like to try and do the same thing.
