Will the dynamics change much in Maine if Olympia Snowe is teabagged and loses the primary? I assume if she loses, it will give Democrats a big edge and could shift the race into the Leans Democratic category and creating the chance for a pickup - unless she pulls a Lisa Murkowski and runs as an Independent, in which case she would probably very likely win with well over 50 percent of the vote.
I think it's for that very reason the GOP won't let her fall in the primary. If they do, she's likely to pull a Murkowski and discredit the party.
