Matt Steinglass thinks the Republican field this year was bound to be terrible regardless of candidate:
Republicans have buried their differences by assaulting everything Mr Obama supports, and because Mr Obama is a pretty middle-of-the-road politician, that includes a whole lot of things that many Republicans used to support. They are disenchanted with their candidates because their candidates are incoherent, but their candidates are incoherent because the base is incoherent. If the GOP wins this election, the party's leaders are going to be confronted with that incoherence pretty quickly. Unfortunately, so will the rest of us.
