I’m no fan of Mittens, and wouldn’t consider voting for him unless it was down to him and he and Obama. However, I think there’s a large chance he ends up with the nomination. In fact, I think he’s likely the odds-on favorite.
It doesn't seem like the electorate at large would vote for Romney. Some RINOs like him, as well as some moderates who don't pay attention.
But there is just something about him that turns a lot of ordinary people off.
