If your point is that Mitt will be damaged by the MSM for his Mormonism, then what's new? Perry, if he is the nominee, will be castigated for being a Texas redneck, a bible-thumper, and a crony capitalist. Cain will be castigated for being an Uncle Tom.
Whoever we choose will be dumped on. Mitt will be damaged more by Romneycare than Mormonism if he is the nominee.
