The staff of incumbent senator Jim Talent decided to go after the McCaskill campaign for a filing that got lost in the mail. There's a receipt showing that the filing was sent, so there's not really an issue, but the Talent gang decided to make the competence of Ms. McCaskill and her staff an issue. Unfortunately, the staffer responsible for the filing died after having sent the filing
, so the whole thing looks a tad crude.
Jim Talent: unpopular senator, insenstive prick.
