Coleman a Centrist?

As the Minnesota Star Tribune reported today, it is becoming common to see once far right conservative members of Congress move to the center. Senator Norm Coleman, who is up for re-election in 2008, is slowly becoming more of a moderate. Is this a sign he is worried about his chances of re-election? Has he recognized that the American public overwhelmingly rejects the social policy of the far right? This will be yet another seat to watch in '08.
