No. Cruz, providing he doesn't pull a Perry, will stand alone on immigration (dig a moat, add gas and gators), life (new car smell trumps SweaterVest), Supremes (original intent a la Nino and Scalia), foreign policy (dislodge IS with boots on ground). The whole package that Perry couldn't deliver.
Rand OTOH pulls the Paulists back off the pine, so it's a new voting vector in what were zer0-sum primaries the last two times - if they're willing to vote GOP.
FatBuckle is the wild card but his presence doesn't hurt Cruz as much as it hurts ...*drumroll*...eventually...Mitt. In fact, I think FatBuckle will run as a mano y mano thing he needs to satisfy against Mitt - talk about a dream scenario for Cruz.
“Cruz, providing he doesn’t pull a Perry, will stand alone”
Thats the whole problem. He will stand alone because all the moral cowards will flock to the ‘winner’ because thats what they will again be told to do.
