The show is just starting BC but I can't imagine why you've already bailed on Rand's chances and then in the next sentence mention that those bozos don't have a chance as if they're worthy of it. Granted, bush, christie and rubio suck hard and I'm willing to put walker on that list atm, let's not do the backpacking for the establishment and their candidate pickings which is the aforementioned minus Rand - included in. BC, you must be in the US to bust out them thoughts.
It will be extremely tough for Rand to secure the GOP nomination, as all the other (establishment) candidates will come together to prevent him from winning it. Even if he is leading with 30% support, the remaining 70% will unite against him.
I'm not saying it'll be a walk in the park but if he can manage to take Iowa and NH (the first two) then he'll be riding momentum into SC. Also, you'll see a few or more dropping out after the first two contests and then the supporters will divvy up and go their own way. However, the establishment is definitely funding many of the other candidates so if their Ace - Bush doesn't pan out, they have Walker and Rubio still their back pocket. Many conservatives are being played for fools by buying this inflated candidacy of Walker and the establishment is loving that as it's less supporters/votes for Rand. But, it's still early and there's lots of campaigning to go. If you checked out my thread on Rand, you'd see he has the highest amount of people seriously considering or might consider voting for him of all other GOP candidates per my link from Bloomberg recently.
