I wouldn't hold that run against her in terms of elective success. It just wasn't happening that year, no face time or money, though she made a good impression on the electorate. We elected a conservative reformer (or, alternatively, ex-Democrat Angus King) instead.
Ever since she got to run against Joe Brennan she's been pretty golden. Sometimes all you need is that one big break.
Angus King, a Conservative reformer ? King just struck me as nothing but a liberal rodent. I don't think Maine has had a halfway decent Governor since Jim Longley, Sr. in the late '70s.
