Has Mitt Romney reached his Harriette Myers moment?

Remember during the GWB administration that all of the Republicans were gung ho for GWB, until that magic moment when the coalition just collapsed? That moment occurred around the time that Harriette Myers was nominated for the Supreme Court. That is the time when the Republicans started looking at each other and realized that what everyone else was saying about GWB was true. GWB was really an idiot.

Has that time come for Mitt even before the election?
