As many people have already pointed out, Mitt Romney's stated policy preferences last night differed greatly from Mitt Romney's stated policy preferences through the campaign to this point. What we saw last night was a Romney much more comfortable with the idea that tax revenue is an important part of keeping the government functioning at a healthy level, a Romney much less comfortable with the idea of cutting taxes for the rich, a Romney much more concerned with the notion of opportunity and fair play than with freeloaders ruining the economy.
