80% of voters have a favorable view of Colin Powell.
19% have a favorable view of Rush Limbaugh.
So, of course, Cheney picks Limbaugh, who is about as popular as the Republican party right now. From ThinkProgress:
CHENEY: Well, if I had to choose — in terms of being a Republican — I’d go with Rush Limbaugh, I think. My take on it was that Colin had already left the party. I didn’t know he was still a Republican.
And that’s why we want Cheney on television as much as possible. Keep digging the GOP’s own grave, Dick. Keep telegraphing to the country just how conservative and far to the right today’s Republican party really is.
