I honstly don't see why this is a big deal
As you pointed out, the whole idea of a caucus is to convince people to vote for your guy. Soooo, that's what the Cruz campaign did. And that's also what the Rubio campaign did.
Yet, here everyone is, piling on Cruz, making this into some kind of nefarious deed, like he stooped to some level, but he didn't. And his campaign staff, didn't either. They are campaigning and used the information that Carson himself put out there.
And the fact that there's not one peep about the Rubio camp doing this too, just proves, it's all political hyperbole, in an attempt to demean and attack the only REAL Conservative Candidate....the best candidate, we've had since Ronald Reagan. And it's BS!!!
So sad, to see so many, jumping on that bandwagon... :(
