Moderates, who are moderates for a reason, take swift action for one reason and one reason only: to halt conservatives and help democrats.
Ron Paul just tied Romney in Maine. They’re attempting to halt a conservative tide and shore up the gates where they can. A democrat sitting in Snowe’s seat could deny a republican majority in the senate, and therefore assure Harry Reid’s oligarchic control.
Moderates always help democrats.
You are most likely right. she is most likely doing this to help the Rats maintain their Senate majority. She always was a RINO.
