In the fall, Rick Santorum was counted as a goner - Bob Casey had a very strong lead of over 11% and Santorum's numbers had slipped well below the 50% point which indicates danger for an incumbent. It's spring now though, and the most recent polls indicate signs of intelleigent life in Pennsylvania. Santorum maintains a two to one cash on hand edge over Casey and Casey's pro-life stand has made him persona non grata to quite a number of Democratic fund raisers.
The poll also highlighted the current schizophrenia afflicting those who respond to polls - 53% are in favor of 'throwing the bums out' while 50% say 'but not my bum'. That number is a little low historically, usually my bum draws 55% or so.
A sign of impending change? Yes - if the percentages hold up through Labor Day. And Labor Day is only 120 days away - what could change?
