In years past, the march toward Election Day brought discord to Carlos Cancino's home in Edinburg.

"My wife and I used to get into big old arguments during the elections, because she doesn't like Trump," Cancino said.

"And I was a Trump supporter. We used to literally fight and not talk for, like, several days." But this year, Cancino, a Latino small-business owner in the Rio Grande Valley, has done a political 180. Angry over the state of the economy and high prices, he has soured on Trump - and plans to vote for Democrats.
