In a nod to the wave of conservative lawmakers who arrived in Washington this week, House Republicans today unanimously adopted a ban on earmarks, the lawmaker-requested funding for pet projects that became a black-eye for Congress during the past decade.

The House ban, which will apply to the entire 112th Congress, follows a similar move earlier this week by Senate Republicans after Minority Leader Mitch McConnell of Kentucky reversed his long-standing support for these individual member requests.

The House measure was offered by Rep.-elect Sean Duffy, the Wisconsin Republican who won the House seat of retiring Democratic Rep. Dave Obey, who has been Appropriations Committee chairman.

While the vote is an obvious nod to the new Republicans, it’s also a big win for House Minority Leader John Boehner, the speaker-in-waiting, who has never requested an earmark and tried — unsuccessfully — for years to impose a ban.
