Last week we focused on a 17-year-old who caucused this past weekend for Hillary Clinton. Imagine being a first-time caucus participant, 21-year-old Republican and undecided. We’ve found him, and intend to follow him through the process Tuesday February 23, to see if he ultimately is pulled to one side.

“Undecided, correct, yeah,” says Matt Weber.

Weber is a software engineer in Reno. He comes from a political family, so going to the caucuses wasn't even a question. What is the question: to whom will he throw his support?

“I like him (Cruz) because I like his stance on gun control, you know keeping the second amendment rights, keeping them free. I like him (Rubio) because he has a similar stance. It is more the lesser of two evils for me because I'm not a huge fan of Bernie Sanders,” says the 21-year-old.

Unlike the Democratic caucuses in Nevada, Republican caucuses are straw polls. Registered Republicans can stop by their caucus locations, sign in and select their preference. They can then go home.

They can stay, however, and listen to their friends and neighbors about why they prefer one candidate over another. Because he is undecided, Matt says he will stick around to hear the most compelling arguments for Ted Cruz and Marco Rubio. That could be their stance on Obamacare.

“The price of health care has gone through the roof. And I don't like particularly that I am paying for peoples' health care, they are making, granted they are not making a lot of money, but why am I paying for it?” says Weber.

Weber says neither John Kasich nor Donald Trump seems very presidential to him.

With the razor-thin margins between second-place Rubio and third-place Cruz in South Carolina, supporters at North Valleys High School will have their eyes out for undecided voters like Weber to win over Tuesday night.
