Greg Sargent at the WashPost's Plum Line blog writes about a late attack line from the Specter camp on gun rights:

So it's come to this: In a bid for conservative and rural Pennsylvania Dems, Arlen Specter is now using targeted ads to attack Joe Sestak for getting an "F" rating from the National Rifle Association.

In a targeted way, Specter also seems to be touting his vote against the assault weapons ban -- a vote he took as a Republican. One wonders how this ad would play among urban Dems in Philadelphia -- if they ever were to hear about it.

At the Inquirer, Fitzgerald and Infield mention the gun debate toward the bottom of their story today:

Gun control emerged as a last-minute issue in the Senate race, with Specter raising Sestak's F rating from the National Rifle Association in online ads in conservative areas of Western and northeastern Pennsylvania.

Sestak has sponsored legislation to reinstate the federal ban on the sale of assault weapons, which expired in 2004. Specter was still a Republican when he voted against a 10-year extension of the ban.

The assault-weapons ban has not been a dominant issue in a race that has turned on character, but Sestak's campaign clearly hoped that Specter's position would cost him support in Philadelphia, which polls show is his strongest region
