No, I can't yet call a winner in the big impeachment contest yet; sorry, John McNulty, all Trent Franks has done is to say he'd support impeachment. For the contest to produce a winner, a Member of the House would have to actually file a resolution.
Grounds? Yeah, like those are necessary. But if you're interested, here's the WorldNetDaily "story" with Franks's position; it's over the DOMA decision, for what it's worth, although WND has various impeachment supporters cited in the story who have other reasons for impeachment. Steve Benen has more.
Guess I'll go ahead and re-open the contest. Leave your prediction for the first formal impeachment resolution (Member, date) below. Already taken: Bachmann, Brown-Waite, Wilson, Paul, Braun, Kucinich, McCain (my favorite one so far), Foxx, Kesha Rogers, Steve King, Buchanan, Issa, Gohmert, Schock, Schmidt, Blackburn, Poe, Boehner, West, Franks, and Nobody. Lots of good, creative symbolic dates in the earlier post, but I won't repeat those here.
