Ingraham, a vocal opponent of immigration reform, made the warning during her radio program on Thursday.
"I think a populist pitch is a winner across the country —in Hispanic, white, black communities, I'm telling you it is a winner," Ingraham said on her radio show on Thursday, according to The Hill. "We can peel off some minority voters, focus on their wages, their renewal. I'm telling you, it's a winner. Not this old Chamber of Commerce, faux-conservative, big business message. That is a crony capitalist disaster. And I'm sorry, but that's what the Bush folks represent and that's what the Bush nomination will do. It will lose."
Ingraham has often said that supporting immigration reform is a losing position for Republicans. During the 2015 Conservative Political Action Conference, Ingraham interviewed New Jersey Gov. Chris Christie (R) and posed immigration reform questions that disparaged Bush.
Bush has repeatedly argued for changes to the country's immigration system to incorporate undocumented immigration. Earlier in March, Bush said that giving a legal status to undocumented immigrations is the "only serious, thoughtful solution."
