In an interview with CNN's Fareed Zakaria for Sunday's "GPS" program, President Bush's former secretary of state said his party's attempt "to use polarization for political advantage" backfired last month.
"I think the party has to take a hard look at itself," Powell said in the interview, which was taped Wednesday. "There is nothing wrong with being conservative. There is nothing wrong with having socially conservative views - I don't object to that. But if the party wants to have a future in this country, it has to face some realities. In another 20 years, the majority in this country will be the minority."
Powell, who crossed party lines and endorsed President-elect Barack Obama just weeks before the election, said the GOP must see what is in the "hearts and minds" of African-American, Hispanic and Asian voters "and not just try to influence them by... the principles and dogma."
"I think the party has to stop shouting at the world and at the country,"Powell said. "I think that the party has to take a hard look at itself, and I've talked to a number of leaders in recent weeks and they understand that." Powell, who says he still considers himself a Republican, said his party should also stop listening to conservative radio talk show host Rush Limbaugh.
"Can we continue to listen to Rush Limbaugh?" Powell asked. "Is this really the kind of party that we want to be when these kinds of spokespersons seem to appeal to our lesser instincts rather than our better instincts?"
Zakaria's full interview with Powell will air Sunday at 1 p.m. ET on CNN.
