I agree with Flyers on this. Hoeffel would have defeated santorum, and close to the 8-10 range Flyers predicted. It obviously would have been closer, but the difference between hoeffel and Casey is not going to make up an 18 point margin, nor it will make up 14 points.
Doing some math for a minute outside of the Philly metro area (Phill, montco, Delaware, Chester & Bucks) Casey won by 8.8%. Assuming that with Hoffel on the ticket the Metro Philly area puts up similar #'s as it did with Casey, Santorum would have needed to win the rest of the state by 17 points in order to make for his loses in SEPA.. In 2004 Bush won the rest of the state by just higher than half that 9%. So in order to beat Hoffel, Santorum would have had to almost DOUBLE the margin outside of SEPA that Bush had 2 years earlier. Umm no.
Hoeffel still would have won PA, but the DSCC would have had to give Hoeffel more money because it would have been more competitive. As evidenced by vote totals, we needed every penny in VA, MT, and MO. I'd rather have a Democratic majority with a moderate Dem in PA than a Republican majority with a liberal Dem from PA.
