Caitlin McGrath, 19, a volunteer with McSally, made 400 calls today to help get out the vote.
"Every positive market call was just a motivator and it made you want to keep going," she said. Now, she's at the GOP fiesta, hoping to see her efforts pay off.
"I'm hoping to see that Martha McSally wins, obviously, and I'm really hoping to see a change in the economy, especially for us young people," she said.
A recent high school graduate, McGrath was excited about voting in her first election.
"It's one thing to play a part, and it's another thing to say that I am voting for this person because she is the right person for what I want," McGrath said.
