Yeah, there was no doubt - since the Governor of Idaho is a Republican and in that state the Gov. gets to appoint a Senatorial midterm replacement.

Had Craig been representing a state where a Democratic Governor would get to appoint his replacement - or maybe even a state that calls for a new election to replace a Senator midterm - , you can bet the Rep. party would've had a helluva lot more "doubt" re asking for his resignation.

Oh, and I'm on board with you folks who object to someone being prosecutable merely on the basis of ambiguous (possibly totally innocuous) postures, gestures, etc. (I'm reminded of an episode of "L A Law" in which one of the attorneys was "busted" by a plain-clothes policewoman because he asked a waitress in a Japanese restaurant for several culinary items including a "hand roll."   It was not till the judge saw the full complaint that it was obvious to her that he was ordering sushi.)   

In Craig's case, if the officer is to be believed, it's the entire pattern of actions that points to his probably having been trying to solicit a "hookup."   Peer long and repeatedly into someone's stall. Let your foot wander into their stall and tap their foot. Block the view from the front of the door with your briefcase. Wave your hand under the stall divider. Etc.

I still say nothing he did should have been illegal except for the voyeurism, though.

Does signalling another guy in the john that you'd like to have sex with him necessarily mean you're asking to do it right then and there?
