McCain has no excuse for not being there, as Obama and Clinton cast their votes.
Sure he does. His excuse is that he was 'too busy campaigning' to take time off to vote. /s
After all, this way he can pathetically pretend to ignore the vote--
and avoid even MORE controversy then he would have received if he had sided with the democrats (which he obviously would have if not for that darn, pesky, annoying thing limiting his real feelings--the GOP PRESIDENTIAL NOMINATION).
