I would say he his. His involvement with the Lakewood, WA police massacre suspect will hurt him, as will his staunch conservatism. You cannot win a presidential election in this day in age by being on either extreme. One has to campaign close to the center and then slowly move to toward one-sided governing, like President Obama has done. He campaigned from the center-left, but is governing from the left. President Bush even campaigned from the center-right, but governed farther to the right from where he campaigned. I just don't think Huckabee knows how to campaign from the center just like Sarah Palin wouldn't know how to. You can win the primaries from the fringe, but not the general election.
No. Obama is governing from the right.
Obama's governing for his 2012 run, not any ideological standpoint.
