Lots of early exit poll results are floating around. Despite Clinton's constant refrain about Obama going negative -- others saw him engaged more in self defense -- two thirds of Pennsylvania voters thought Clinton attacked unfairly, 49 percent thought Obama did. Even among white women -- 64 percent thought Clinton was unfair, 53 thought Obama.
First time voters reportedly broke heavily for Obama, but late deciders (the final week) broke for Hillary. Drudge has it a four-point race (for Clinton) at the bottom line -- but don't take that to the bank. More links are here.
