From Greg Sargent at The Plum Line -- New DNC Ad Rips GOP As Party Of Vitter And Ensign:

The Democratic National Committee is going up with a tough new ad on DC cable hitting the GOP as the party of David Vitter and John Ensign — a response to an earlier RNC spot targeting Dems over Charlie Rangel and Eric Massa. [...]

The ad seems designed to put Republicans on notice that if they use the Rangel/Massa stories as ammunition, the Dems will respond with a howitzer blast. The spot implicitly invites Beltway insiders and media figures to make the comparison — and to call it one way or the other.

It's good to see the Democrats hitting back on this but as I said before, they're not likely to get much help from the media on this. The Republicans put one of these out and they're getting free air time on every one of the cable news shows. I didn't catch anyone showing this one today. I guess we'll see if any of them pick it up next week.
