Mitt Romney cannot win the Republican presidential nomination. He is a man who seemingly entered the race because, after a long and successful working life, he could think of nothing more impressive to top it all off than being President of the United States. From last spring to this very moment, much of the Republican Establishment has been solidly, viciously, in his corner. And yet he cannot win. Most people, when their candidate looks hopeless, turn to another available candidate who might be satisfactory. The Republican Establishment, which is not like most people, is beginning to murmur about a brokered convention. They are determined to get what they want, by hook or by crook, by Drudge or by Fox.
