One of the surest ways to judge whether some one has the "chops" in elections is whether or not they won their election. The loser by default is responsible for losing his campaign and that is exactly what Romney has done, he lost therefore he is responsible for losing. All this other tripe about long primaries, incumbent presidents, etc. is nothing more than excuses. Romney had the best environment in thirty years to unseat an incumbent president and he didn't. End of story. And let's be honest Romney was only a ersatz Republican in the first place. He has been on the left of the conservative political spectrum.
