Very interesting scenario... but I really can't see MTG getting the nomination.
This really isn't the first time where a conservative said their preferred candidate wouldn't be even a good national candidate let alone win and then either almost or does become a national candidate. In 2008 and 2012, Huckabee and Santorum gave the establishment a run for their money. In 2016, they actually did get the craziest guy in and he WON. In the lead up to 2012, many LDS folks lamented that Romney would never get it.
