"The only way we lose this election is if we beat ourselves and that is very possible, but we are getting creamed with non-white voters," said Sen. Lindsey Graham, R-S.C., who said he's "98.6% sure" he'll run for president.
"We'll lose" if Republicans don't improve their chances with minorities, said Graham.
Speaking to Susan Page on USA Today's "Capital Download," Graham explained: "I mean, we've got a big hole we've dug with Hispanics. We've gone from 44 percent of the Hispanic vote [in the 2004 presidential election] to 27 percent [in 2012.]
"You'll never convince me ... it's not because of the immigration debate," said Graham, who is the only contender for the GOP bid that supports a pathway to legalization before tackling border security.
