Kerry Eleveld has an article up with anonymous Congressional sources blaming the Senate for ENDA falling behind. The DADT deal has to pass the Senate before ENDA can be considered in the House (it's in the Constitution, somewhere in one of the boring parts), and they couldn't have been working on ENDA earlier this year like they said they would because the Congressional session just started three weeks ago.
Plus ENDA needs the approval of Republicans to pass, even though the DADT deal was just attached to the National Defense Authorization Act without 60 votes, but it's different for ENDA since no one in the Senate has had the time to think of how to pass ENDA in the last year and a half. It's not like the Senate is working on any bills related to jobs or employment this year, so they can't just attach it to something else.
You see, mean, mean Republicans like Coburn or Demint might filibuster ENDA, which actually means that they'll threaten to filibuster it and Harry Reid won't force the issue. He could, and then Republicans would be forced to filibuster the bill on national TV, reading the phone book to prevent basic protections for LGBTQ people that most Americans think are already the law, and look like a bunch of out-of-touch Moral Majority scolds from the 1970's. That just wouldn't be fair to the GOP. Why, they might get mad and start opposing the Democrats' agenda.
Most importantly, it's a very difficult bill to pass since only 89% of the American public supports it. Only 66% of people in Utah are OK with LGBT job protections, so if Democrats push the issue they might alienate Utah's most conservative voters and lose their chance to replace Orrin Hatch with Noam Chomsky. Plus the transgender protections are there, and people who work in the Senate are simply helpless to get the Senate aware of how firing someone for who they are is wrong. It's transgender people who need to "own this," not the Senate itself, because Senators and their staffers are simply passive bystanders in this ballad of folly and squalor we call American politics.
But don't question the party's, or Nancy Pelosi's, commitment to ENDA. Obviously they really want it to pass.
