Mousel’s 19-year-old son, Zac Mousel, said he likes that Trump was once a Democrat.

“He’s not so Republican that he’s a closed door, and I think that’s what every politician needs to be,” said Mousel, who is studying architectural engineering at a tech college and plans to vote for Trump. “They need to be interested in looking out for the betterment of the country, not just the betterment of your party.”

This theme of unity has been in Trump’s rally speeches for months but is often overshadowed by his headline-grabbing attacks, insults and controversial proposals.

Trump has said he expects to win not only the votes of white working-class people who appear to make up his core base, but also African Americans and Latino voters attracted to his economic promises of more jobs and better pay. He has chastised President Obama for not being a “cheerleader for the country” and instead allowing Americans to become divided, especially over racial issues. When protesters turn up at his rallies, Trump often tells the crowd — after the protesters are escorted out — that he could win them over if they would just give him the chance.
