Ok, so 2012 polls are basically meaningless - but that doesn't make them any less fun to talk about. PPP is out with a new 2012 survey showing Barack Obama leading all four potential GOP contenders (sorry TPaw and Jindal), though he's only over 50% against one of them and another runs surprisingly close:

Obama 47%, Huckabee 44%
Obama 47%, Romney 40%
Obama 49%, Gingrich 41%
Obama 52%, Palin 38%
