Romney's problem

This Corner post by Jonathan Adler (who was then a fellow Fred-head) from a few weeks back pretty much nails my own reservations about Mitt Romney:

What's Romney's problem? For many folks (my self included), it is a perceived insincerity. I too often get the sense that Romney is saying what he thinks folks want to hear instead of what he believes. It isn't just the "evolution" of his views, it is also the small things: The small, subtle exaggerations that arise when Romney is trying to ingratiate himself with various groups. (Remember Romney the life-long hunter?) The blatant pandering to the auto industry in Michigan in a way that suggests some very unconservative views. Romney's MBA style does not help much here, as it reinforces the perception of Romney as someone who solves problems without much regard to underlying ideological principle.
