Instapundit reports that earmark reform has passed the House, which can only be a good thing. According to the official tally, all four of Colorado's Republicans voted in favor, joined only by Democrat John Salazar. Democrats Diana "Oil Conspiracy" DeGette and Mark Udall, both in very safe Democratic seats, voted against.
With records like these, discussed at To The Right, you can see why the Dems weren't thrilled with the rules change.
The rules change essentially eliminated anonymous earmarks in the House, and takes effect immediately, although it's not clear how much difference it will make this close to elections and this late in the budget cycle. Also remember that we're in the McCain-Feingold blackout Incumbent Protection period, preventing non-Party media ads criticizing incumbents who are running for re-election.
Still, it's a good start.
