Is this a national poll or a particular primary?
um.. read the title...
It says "Pennsylvania" in the title.
Even in this poll, 47% of Pennsylvanians think Obama deserves reelection, that's a steady increase from Aug 2011. Only 4% don't know.
45% of registered PA Republicans are still "Making up their minds" on who they'll vote for in the primary.
Also, Mitt was overwhelmingly the second choice so if Santorum falls, Mitt rises in PA.
