Veteran GOP consultant Mike Madrid, who was hired by the party in 1996 in the wake of Prop. 187 to help the party woo Latino voters, said he finds the current immigration debate among Republican candidates "a little heartbreaking."

Last night, Ohio Gov. John Kasich warned his party about nominating a presidential candidate whose immigration rhetoric is divisive.
"Do the Republicans actually think that they can win an election by scaring every Hispanic in this country to death, scaring them to the point where they think their families are going to be torn apart and disrupted?," Kasich asked.
