Calling for his divided party to widen its ranks, Powell declared, "I am still a Republican."
In an appearance on CBS' Face the Nation, Powell responded to attacks from former Vice President Dick Cheney and talk show host Rush Limbaugh, saying they are "not members of the membership committee of the Republican Party."
"Rush will not get his wish, and Mr. Cheney was misinformed. I am still a Republican", he said. "I would like to point out that in the course of my 50 years of voting for presidents, I have voted for the person I thought was best qualified at that time to lead the nation. Last year, I thought it was President Barack Obama. For the previous 20 years, I voted solidly for Republican candidates."
Earlier this month on the same program, Cheney was asked about a dispute between Limbaugh and Powell over the role each plays in the GOP. "My take on it was Colin had already left the party. I didn't know he was still a Republican," Cheney responded.
Powell said Sunday that he didn't want to trade insults with Limbaugh, but that he thought it was "unfortunate" Limbaugh framed his support of Obama along racial lines.
Limbaugh, on his radio program, argued that Powell supported Obama "solely based on race."
Discussing divisions over the direction of the party in the wake of its losses in the 2006 midterm elections and 2008 presidential election, Powell said Sunday the party should expand its base.
"I have always felt that the Republican Party should be more inclusive than it generally has been over the years and I believe that we need a strong Republican Party that is not just anchored in the base but has built on the base to include more individuals. And if we don't do that, if we don't reach out more, the party is going to be sitting on a very, very narrow base," he told "Face the Nation."
Powell added, "Let's debate the future of the party and let all segments in… What we have to do is debate and define who we are and what we are, and not just listen to dictates that come down from the right wing of the party."
