I follow SC politics pretty closely. Trust me when I say Nikki Haley is nothing, repeat nothing, like her image. She is as disingenuous a politician as I've ever encountered.
There is a reason Graham is wanting to play front man. I don't know what the reason is but rest assured a politician used to his comfortable DC interviews is giving up a lot of safety by going out on the campaign trail where he will no doubt be treated to raw comments about a number of his position. This move on Lindsey's part is not his idea. His handlers are pushing him out. It remains to be determined the ultimate reason.
