He has already been the butt of plenty of late night comedians’ jokes. And now Rick Perry will go into the lion’s den tonight and sit down with David Letterman.

Meanwhile, some top Republicans and Perry donors are suggesting that the debate mistake could spell doom for the Texas governor.

Tonight, he will try to explain the cringeworthy moment in New York with Letterman, part of his effort to change the narrative. His campaign quickly tried to capi­tal­ize on the gaffe, arguing that there are lots of agencies that Americans would like to forget, and directed people to his Web site to pick an agency that should be eliminated.

Perry, who has always admitted to not being a strong debater, has tried to make light of his debating skills in the past, saying that if he debates enough, perhaps he will actually become skilled at it.

Obviously, that has yet to happen, and Perry woke up this morning with a huge problem for his campaign, which has faltered since August. The humor route has been tried before: Sarah Palin, for example, went on “Saturday Night Live,” which had mercilessly mocked her.

Perry has faced similar mocking for his debate performances and for a speech he gave in New Hampshire. An edited 8-minute reel of the more animated high points of the speech went viral on YouTube.

In a tweet, conservative radio host Laura Ingraham said: “The best way for Perry to recover would be an appearance on SNL this weekend.”
