While in a perfect world we'd get rid of the Senate, that's not gonna happen. Nor is getting rid of the filibuster.
What Obama and testes-less Harry Reid SHOULD do, however, is make the Republicans filibuster. Make 'em look stupid on national tv a couple of times. No more of this just letting them threaten shit. If health care is a couple of votes away, make them stand up and filibuster a plan that will drive down costs and insure millions more Americans. See how that works for them in 2010 and 2012.
These are Democrats we're talking about, tho. I'm just shocked every day that goes by where they don't ask the Republicans if it's ok for them to go to the bathroom, so making the GOP filibuster is probably out of the question.
