It's coming from inside the House

Republicans were successfully able to modify the bill requiring background checks on all gun sales — a marquee vote in the new Democratic-led House — with a provision targeting undocumented immigrants who try to purchase weapons.

Democrats learned the specifics of the GOP motion only minutes before the vote.

The surprise win for Republicans — enough Democrats joined with the GOP to successfully attach the immigration related amendment to the guns bill — was the second such setback for Democratic leaders in recent weeks.

Earlier this month, Republicans used the same maneuver to successfully force Democrats to add language condemning anti-Semitism to an unrelated bill to halt U.S. involvement in the Yemen war. The resolution passed, but the GOP amendment ended up derailing the Yemen resolution in the Senate.

Speaker Nancy Pelosi later raised the issue at her weekly meeting with leaders of the various Democratic interest groups — from the Congressional Black Caucus to the Blue Dogs. Pelosi said it was disappointing that veteran lawmakers who had been awarded spots on coveted committees including the Ways and Means and Appropriations panels then chose to turn around and vote with Republicans on Wednesday.

The maybe they should stop picking people for committee appointments on the basis of how much money they raise for the DNC and start choosing people who are appropriate for the committee. Or people they know will vote with Democrats every time, for that matter.

Majority Leader Steny Hoyer (D-Md.) and other top Democrats are weighing revising the House rules to require Republicans give them more notice on specific procedural votes, known as a “motion to recommit,” a wonky tactic that the GOP has used to force Democrats to vote on a range of controversial issues since January.

What they need to change is the ability to tack on unrelated amendments altogether.

Pelosi, Hoyer and Clyburn have watched with alarm for weeks as Republicans have continued to win Democratic support for their controversial amendments, often from freshmen who have privately expressed concerns about the GOP using these votes against them in campaign ads.

Pelosi has met with the freshmen multiple times, encouraging them to stay unified and vote with the party — thus letting the air out of the GOP’s attack balloon. But multiple freshmen in GOP-targeted districts told POLITICO earlier this month they have no plans to change their strategy.

If true, that's just plain sad. What was the purpose of Americans electing Democrats if they're going to vote Republican? On the other hand, if they really are voting the way their contituents want them to, so be it. That's the only way to end the hell hole of partisanship that is currently our Congress.

...but hey, do what you want...you will anyway.
