Those old Republican hot buttons are growing cold. For proof, check out a recent interview with Mitt Romney, a former presidential candidate and ex-governor of Massachusetts. According to TheHill.com, a congressional newspaper that publishes when Congress is in session, ''Romney believes that one way to attract more minorities to the GOP is to pass immigration reform before the next election, saying the issue becomes demagogued by both parties on the campaign trail.'' The article also quotes Romney as saying, ``We have a natural affinity with Hispanic-American voters, Asian-American voters.''
