After blocking measures on habeas corpus and Iraq yesterday, Senate Republicans will seek to condemn MoveOn's Petraeus ad today. Sen. Barbara Boxer has proposed an alternative resolution that includes condemnations on other political attack ads, too, including on John Kerry in 2004 and Max Cleland in 2002.

Late Update: No word on whether there is a statue of limitations on congressional condemnation of attack ads.

Later Update: Reid and Levin to vote against GOP resolution and support Boxer alternative.
