Absentee ballots are likely being printed in all 50 states already; distribution begins .... likely by October 4th. Theres a bunch of state laws involving changing the ballots within 30 days of an election -- too complex to make guarantees in all 50 states. The arguments are sound, but I personally believe it's too late in the game for this. A month ago? Yeah, maybe.
I'll throw one more reason to SUPPORT this line of thinking, however: we know that a lengthy campaign would not leave Hill clean -- but an absurdly SHORT campaign, and she has a shot, IM(very afraid)HO.
