Interesting. My personal take on the GOP's candidates;
Palin- Probably won't run. She has an excellent gig going around spouting platitudes and appearing on TV for huge fees. If she runs and loses, the magic is destroyed. If she does run, she's got a GREAT chance at the nomination and the only way she avoids utter obliteration in the General is if the economic gets substantially worse- yes, worse than even now. There is literally no precedent of a candidate with remotely close to the awfulness of her numbers winning even a state-wide election let alone a national.
Romney- Will definitely run, will almost certainly lose because he's too "moderate" (He's not really but he is for the modern GOP because Romneycare was almost the same as Obamacare) and is a Mormon
Huckabee- Will probably run, probably too little appeal outside Christian conservative base to win the nomination
Gringrich- Will probably run if Palin doesn't, FAR too extreme in recent statements to do well in the General
So I think all four front-runners will have MASSIVE handicaps in either General or the nomination. Obama will be somewhat weak in 2012- but the GOP has a shockingly terrible field of front-runners. I think their best shot at victory in the 2012 General is an outsider with more credibility- someone like Mitch Daniels would be an EXTREMELY significent threat. The problem is that 2010's Senate elections showed time and time again that if you're conservative enough for the GOP base, you are almost certainly FAR too right wing for a mainstream electorate anywhere outside the Deep South. So those candidates with the best shot at beating Obama will have the hardest time winning the primaries.
I would love to see President Obama have an actual debate with the Majority and Minority leaders in the House. Maybe substantive dialog could lead to compromise (*gasp!*) and a way forward.
It's not quite that but might I recommend Obama's performance with the Republican Senate Caucus in around January or February of this year? A barnstorming performance, and definitely worth a view.
P.S. Ed Miliband looks like a bit of a tool as leader of the opposition during QT.
It's interesting that you say that because Miliband has gotten an extremely positive press reaction - and a surprised one- for his performance at PMQs, clearly knocking Cameron off his guard quite a bit. I think Cameron has lost steam in the transition; he still instinctively asks questions and dodges rather than answering.
