Don’t know Portman, but obviously Gingrich should he get the nomination, CANNOT pick someone who the MSM has already tried to destroy as being divisive, extreme, polarizing, or incompetent. By that I mean, for example, Sarah Palin.
A Veep choice has to be seen as a reasonable, soft-spoken and well-meaning plodder. Gingrich will choose wisely if he becomes the nominee ( I hope he does, of course).
Well, that description fits most of the occupants of Ohio, so Rob Portman has a chance.
