You hit the nail on the head.
From the start, I believed that Linda Graham’s entrance into the race was to try to prevent Ted Cruz from winning the South Carolina primary, hoping that S.C. voters will vote for “favorite son” Graham thereby denying Cruz a win in the first southern state primary.
It will backfire in Graham’s face.
Graham is a stalking horse for Jebbie.
The back end of the horse would be more accurate.
