With all the money they're spending, AE should make all 50 ballots. The Libertarian Party might do it as well, especially as RJ Harris (remember him as a Congressional candidate last time?) is running for President and spending the bulk of his campaign resources getting ballot access in his home state of Oklahoma, which is notoriously restrictive.
I'm curious to see how soon AE rolls out its board members' pre-selected candidate. Rumor has it they have a John Huntsman/Evan Bayh ticket lined up. But they'll probably let their phony online voting process run first.
