Darcy Burner on a Responsible Plan To Get Out of Iraq

This is really not possible. The Democrats don't have enough votes in the Senate to overcome a phillibuster. It takes 60 votes. We barely have 48. One Democrat has been out with a stroke. The other might as well be a Republican.

Burner's running for the House. The House controls the purse strings with a simple majority vote. The Dems have caved to Bush repeatedly and with even less justification over the last two years.

Yes, you are correct. The House controls the purse strings. However, this is done with an appropriations bill. So for example Dennis Kucinich has proposed another one in 2007 that would have stopped the war: HR 1234 (110th congress). It's not gone anywhere even though there are 234 Democrats and 201 Republicans.  It's not even out of committee.
The ones that make it out of committee and go to the Senate get killed there.

She hasn't even been elected yet! How can she be part of the establishment? For the record, she's one of the strongest opponents of the war now running for Congress.

Her closeness to the DCCC, Pelosi, Patty Murray et. al. = being part of the establishment.

Cindy Sheehan's an opponent of the war.
