Well, the Establishment loathes Rand and has been trying to undermine him at every turn. This is to be expected.
As far as TP goes, its hard to say just yet. The problem is Cruz talks a good game to some people.
Personally I have been paying less attention lately, because frankly the state of affairs is too depressing. The bottom line is Joe Everyman simply isnt paying attention, or doesnt have the attention span to understand what he sees.
The Establishment is in full on counter-revolutionary mode, without even a revolution to counter. The amount of money and influence being wielded is unimaginable, not just MSM but even the NRA snubbed Rand.
Will have to wait and see how the primaries play out.
