Reince Priebus said today on Hannity for those GOP candidates who continue to withhold their endorsement of Donald Trump that there could be a political price to pay should they seek the presidency in 4 or 8 years...coming to the RNC for assistance in their campaigns.
After all, he continued, what should a party do if a candidate breaks the rules of the party by not honoring their pledge. There must be some consequence.
He also noted that North Carolina has a rule for its state primary that in order to be considered to be on the ballot a candidate MUST pledge to support the eventual nominee.
So it's not as cut and dried as people might think.
Seems to me Kasich is being a dick, and stupid one at that. The withholding of Kasich's pledge has virtually no impact on the nominee but it could impact Kasich's future.
