I’m still have a sly feeling in 2012, Obama wont run again and it’ll be down to Clinton vs Palin.
We haven't elected a General to the White House since 1956 and by 2012 I expect international relations and defense will be such a shambles that anyone with a military background will be a shoo-in. Obama's pathological narcissism won't allow him NOT to run, even if he leads the Demonrats into the wilderness for the next 20 years. So that's my guess -- Obama vs. a General to be named later.
My take is that the Clintons are rattling Obama’s cage with the hint of a challenge in order to force him to swap her in for Joe. Part of the rationale will be to neutralize Palin’s appeal to independent women.
