Bachmann campaign nervous about potential Perry bid?

Michele Bachmann is riding pretty high right now with decent approval numbers compared to other GOP presidential hopefuls. But her greatest threat may not be in the race yet and her campaign manager Ed Rollins seemed to suggest as much after Bachmann spoke at the National Press Club last week. Following the luncheon, here's what Rollins said about potential candidate Rick Perry, according to Politico:

"Governor Perry would be a very credible candidate. I think we control our own environment, we don't control his environment and at the end of the day, if he wants to get in, he gets in.

[...]

He's got a great [record] — he ought to stay in Texas and keep building jobs there."
