Nice list, with two comments:

1. Jason Altmeier (D-PA) is also skipping the convention. He's a lame duck, having lost to Critz in the primary, but still a congressional incumbent. He'd have nothing to lose by attending, but may be thinking long term. Who knows?
   
2. Colon Bowell is just biding his time. If Romney is leading, be might try to parlay his worthless endorsement into an administration appointment. If BO is leading, he will naturally wait until October to endorse BO again. If they are running even, he might endorse Romney to help sabatoge the campaign.

Altmeier added. Let me know if you hear of anyone else weaseling out.
