I give her 24 hours. As I am writing this, it's 10:48 AM Pacific time. If Sarah Palin is to pull out in time for the Republicans to nominate someone else as Vice President at this convention, she has to withdraw before Wednesday evening. Given that they need a certain amount of time to put someone in place, the hard deadline would be sometime Wednesday morning.
There's so much flying around it would take me an hour to link to all of it. I think the deal killer is membership in the Alaska Independence Party. I'm not absolutely sure that she was a member, but she's clearly associated with it. That's absurd.
24 hours. Noon Minnesota time, September 3rd, 2008.
