He gets an "A" for effort, and his lawyer's getting a big ol' check:
Arguments are scheduled for this morning in the appeal of U.S. Sen. Larry Craig's disorderly conduct conviction for pursuing anonymous sex in an airport bathroom.[...]
Craig is asking to withdraw his guilty plea in the case stemming from his arrest in the summer of 2007 in a men's room at Minneapolis-St. Paul International Airport. Hennepin County District Judge Charles Porter already has rejected Craig's request to withdraw the plea.
I'm not going to bother to look up exactly why he's filing this one. I put his chances of winning at around .01%, because if he had a winning argument, he would have used it in one of his other half a dozen attempts to overturn his guilty plea.
