I think some of them are dumb enough to try it. I also think the smart ones, and there is such a thing as a smart politician, will run away screaming at the mention of it. Even the mildly retarded ones remember the losses they incurred the last time they went after guns.
Nope.
I am a HUGE cynic, but if they didn't have a 2500 page Gabby Giffords Memorial Omnibus Neighborhood Pacification and Gun Crime Eradication Bill ready to go on Tuesday after that Tucson shooting, then they're not going to do it.
The legislation has been written for decades. It's been analyzed into logical blocks, just waiting for an opportune tragedy to propose (or re-propose in the case of portions of the sunsetted AWB) on the floor of the House and Senate.
Even the Senate doesn't have the bawlz to come after the guns. Harry knows he's pretty much at 50/50 and coming across as foaming Pelosi-ites is going to shift the house to a 60/40 in the 2012 Senate races. Harry also barely survived Nevada because he kissed *expletive deleted*ss to the NRA and the shooting community there.
The Senate DOES NOT WANT Tea Party Republicans in its ranks, and they're not going to rock the boat any more. It's the good old boys' club of politics. Jeffersonian values have no place there.
The Senate going after guns would be the end of many careers... most of the blue dog and RINO senators in flyover America would lose their next primaries.
