I really doubt Rand will make it out of the primaries. He's not going to end up fundraising enough money to even stand a chance. The game is rigged.
2016 isn't the only primary. There will be another one 4, and then 8, years later. Rand is still a relatively young man!
The game is rigged, but the GOP operates on an 'it's my turn' hierarchy and is *really* sick of losing the White House to the Dims.
President Hillary (BARF!) is their worst nightmare, and they might be ready to abandon the War On Drugs and other 'social conservatism' BS in a come-to-Jesus moment of existential terror.
