STILL WAITING…. It seemed, for a while, that ABC News and Andrew Sullivan were the only ones obsessing over Sarah Palin’s still-elusive medical records, but this morning, CNN picked up on the story.

With less than 24 hours to go before the presidential election, Sarah Palin still has not released her medical records and there is no indication the campaign is planning to do so.

Two weeks ago, Palin’s campaign told several reporters traveling with the campaign that a summary of the governor’s medical history would be made public before election day.

Reporters were told that details on Palin’s medical background would be released early last week. Last Thursday, after that timeframe had passed, a campaign aide backed off the previous pledge, saying the campaign wasn’t sure when the information would be released.

John McCain, Barack Obama and Joseph Biden have all provided details about their medical history.

I wouldn’t be inclined to care, if Palin weren’t acting so strangely about the issue. Of the four candidates for national office, not only Palin the only one who refuses to release any of her medical records, but as of a few weeks ago, her spokesperson said Palin wouldn’t even answer questions on the subject.

Two weeks ago, though, Palin told a national television audience she would placate “some curiosity seekers” and release her records to the media. When reporters followed up, Palin and her aides stalled.

About a week ago, Palin spokeswoman Tracey Schmitt promised that the records would be released “sooner than later.” The election, of course, is tomorrow. If the materials were going to be released, I thought late Friday night would have been the predictable time. But even that tactical time has come and gone.

Even if there were some logistical delays, such as having materials mailed in from Alaska, it doesn’t take two weeks to get some records together. So, what happened?

The more the campaign has stonewalled on this, the more suspicious it seems.
