Schweitzer would be the best nominee, particularly because he is somewhat ambiguous on whether he is to the left or the right. He is certainly to the left on issues like energy independence, but to the right on issues like gun control. He can appeal to liberals as well as rural areas that might otherwise lean Republican.
Agreed. He's probably going to be the nominee, and he's going to be the kind of moderate that can appear to be on the left and right depending on the issue. Schrodinger's Nominee, if you will.
Schweitzer's probably overall slightly to the left of Obama except on gun control and other big Montana issues.
