With Obama set to announce his choice for Vice President, voters are weighing in on who they think should be his running mate. "100,000 Strong Against Evan Bayh for VP" is a facebook page that describes Bayh as a “career legacy politician who fell hook, line, and sinker for the…war and dragged much of our party with him.” It only has some 4,000 signatories but they're aiming high. Reminiscent of the MyBo page against Obama’s FISA vote there is a clear determination on the part of Obama supporters to hold him accountable.

One can debate just how effective these online campaigns are—Obama did not change his position on FISA, though he did issue an explanation of why he voted the way he did—but, at a minimum, they indicate a level of internal dissent that is healthy.

What about the others on the short list? There’s a lot of talk about Obama’s need to bolster his foreign policy credentials, which seems to be driving the momentum behind Joe Biden. But Biden is far from the kind of progressive running mate many hoped Obama would choose. It appears that Obama’s supposed weakness on national security has eclipsed the primacy of a broader progressive agenda. Is this a failure of the progressive movement?

Here to discuss what the selection process might tell us about an Obama presidency are author and activist Kenyon Farrow, Andrea Batista Schlesinger of the Drum Major Institute, Lisa Witter of Fenton Communications, and the American Prospect’s Courtney Martin.

Continuing our Katrina coverage we have an interview with Monique Harden Co-Director and Attorney with Advocates for Environmental Human Rights. She discusses the impact of global warming on the Gulf region, the continued dredging of wetlands and oil and natural gas exploration, and why the Bush administration’s recovery effort has helped developers but not people.
