Splitting the sane vote

When Lisa Murkowski (R, for now, AK) announced that she would run for her Senate seat as a write-in candidate, I thought that was good news for Scott McAdams, the Democrat in the race. Apparently, I was naive. According to a new poll, Murkowski is splitting the vote of the sane people in Alaska with McAdams, providing Tea Partier and right-wing crank/crazy Joe Miller (now that has to be a made-up name, right?) with a big lead.

Sigh.
