Brannon has also been supported by Freedomworks, a Tea Party-affiliated organization that has been one of the more prominent independent expenditure groups in the state.
"When I hear about, how can you get the youth involved, you do what those men did — tell the truth," Brannon said at CPAC, in reference to Paul, Lee and Sen. Ted Cruz, R-Texas.
But Brannon has been seen as one of the more extreme candidates in the race.
In a 2013 interview with a Tea Party channel, Brannon said food stamps enslaves people and said on a 2012 radio Q&A that Medicaid and Medicare should be eliminated.
Brannon has made attempts to reach out to younger voters through hosting a video contest to encourage college students to show their campaigning efforts on campus.
On his website, it says that young people face higher deficits and debt, surveillance on their internet and technology habits, and that the Affordable Care Act has led to more taxes and makes young people pay more for sicker people.
A poll conducted earlier this year by Pew Research Center showed people between ages 18 and 29 are more likely to say Americans should not give up privacy to ensure safety from terrorism.
But another survey by Pew showed while young people disapprove of the Affordable Care Act, they are also more likely to say the government should be responsible that all Americans have health coverage.
The "education" part of Brannon's website only addresses K-12 education, saying that Brannon would "end federal involvement in education and restore parents’ rights and responsibilities in educating children." Similarly, his website does not address student loan debt or college affordability.
He once said that public education "does nothing but dehumanize students."
In a civil lawsuit in March, Brannon was found to have misled investors in a startup company and was responsible for paying the investors more than $450,000.
Still, the lawsuit did not seem to affect Brannon's candidacy. He is polling at 15 percent — only a few points behind the primary's frontrunner, N.C. House Speaker Thom Tillis, who is polling at 18 percent, according Public Policy Polling.
Brannon is also polling tightly with Sen. Kay Hagan, D-N.C — he has a two percent lead over her, according to polling done by PPP in early April.
With national backing from conservative stars, Brannon has gone from political novice to formidable opponent, and Brannon can potentially force Tillis into a runoff primary.
But in the case of a runoff, Brannon may face a tougher challenge if Tillis and more establishment Republicans face him. And if Brannon makes it to the general election, he will have to battle against perceptions of extremism to unseat Hagan.
