While I believe that conclusive proof that Obama hid a Kenyan birth would convince even the black community that he deserved to be removed, my expectation is that Democrats themselves will engineer his removal to save the Democratic Party (what is left of it) in the 2012 election.
There are 21 Democrat senators up in 2012 and half of them are vulnerable if the 2010 election is replayed including another battle over the tax cuts that Obama has set them up for. These senators and all Democrats are having a horrible time raising money. Obama raised $800 million IIRC in 2008, but the entire progressive wing has slammed their wallets shut and loath Obama now.
To save the presidency and the goodies that come with writing the executive orders in the federal agencies Democrats must have a new candidate in 2012 and they must allow that candidate to get started _now_!
All that bit about traipsing through the snows of New Hampshire is just one year from now.
It’s going to be Hillary. She’s waiting to be begged but she’ll run.
