Can Senator Larry Craig withdraw his guilty plea?

If he can, who can't?

To withdraw a guilty plea under Minnesota law, defendants must prove that ["manifest injustice"] has occurred....

Craig, who has declared he is "not gay" and never has been, has contended in legal motions that he was "deeply panicked"...

But the prosecution has contended that Craig did not panic and was keenly aware of his legal standing during the two months from his arrest date to Aug. 8, when the court accepted his guilty plea and a $500 fine....

[The government argues] that in at least three phone conversations, the senator "seemed calm, intelligent and methodical in his questions" before filing the guilty plea.
