There are several new story lines opening up tonight on the Guard issue. In addition to the bizarre dental records release noted below, a number of news outlets are running with the allegations of former Texas Guard official Bill Burkett, who has said for some time that the president's Guard records were "cleansed" by campaign staffers back in 1999.

The most detailed run-down seems to be in USAToday.

Kevin Drum notes how the authors of the piece have a (good) history with the source, Burkett, thus arguably lending his story more credibility.

In general, Drum's site, Calpundit.com, continues to be the invaluable source in making sense of all the different moving parts of this story -- which documents mean what, who says the president did what when, etc.
