The Associated Press reports today:

Democrats Barack Obama and Hillary Rodham Clinton on Monday joined Republican presidential candidate John McCain and a small band of GOP senators in making a run this week against the billions of dollars in home-state pet projects Congress funds each year.

Obama, locked in a head-to-head battle with Clinton for the Democratic nomination, was the first to declare through a spokesman Monday that he would support a one-year moratorium on so-called earmarks when it comes up for a vote later this week. Clinton followed shortly afterward through a spokesman.

A McCain adviser wrote us with a response: "We welcome the election-year conversion of Sens. Obama and Clinton, two politicians well versed in the art of pork-barrel politics."
