If Romney can't win the midwest or the South, and NY and Cal are way late in teh process, how does Mitt get anywhere close to the delegates he needs? There just aren't enough in New England and the West until California. Mitt really needs Ill., Wisc, Mich, Ind, Ohio, Penn.
I think you answered your own question. Romney gets the delegates he needs, but he does so late in the process, because the calendar is so backloaded this year. He probably clinches the nomination on June 5, when California votes.
