I read a few articles and blog remarks about their first debate. I didn't actually hear it myself. They basically agreed on no drilling in ANWR, and they sparred over whether they'd support a preemptive Israeli strike on Iran (Fitzpatrick - Yes; Murphy - No) and about whether Fitzpatrick is getting some veterans cemetary built fast enough.. They also sniped at one another over the anti-pedophile MySpace bill Fitzpatrick has introduced (Murphy says it doesn't go far enough) and over whether Murphy is a 'carpetbagger' to the district.
But I take it you gathered it helped the incumbent, since you mentioned it in your downgrade, no?
off topic, but I think you could make a case now that PA Senate race should move from Likely to Lean in your rankings.
