A Democratic presidential candidate has not carried the state of Missouri in this century, but some Republicans fear having Donald Trump at the top of the ticket may help Democrats here and give Hillary Clinton a chance to carry the state like Bill Clinton did in 1992 and 1996.

Sam Clovis is a policy adviser on Donald Trump’s campaign. He says Republican critics don’t understand that Trump’s supporters would “walk through concrete walls” for Trump.

“You can’t always trust what you see on TV. Just a thought,” said Clovis.

Clovis said Republicans who are publicly raising these concerns need either get behind Trump, or “shut up” because Trump is winning.

“I’ve seen him in those crowds. It’s mesmerizing. He has charisma and he connects, and normally in the last ten minutes of a speech, it’s emotional,” said Clovis.

Clovis says Trump’s connection with working class Americans will spur turn-out among voters who haven’t BEEN voting for years.
