The Unitparty is the Dems+RINOs ... but I digress.    The Republican Party will cease to exist because of the RINOs and because Trump is neither a Democrat or a Republican.  He owes no allegiance to the party as his 2016 campaign was self funded ... He is the ultimate Independent using the Republican establishment as a vehicle because there was no other way to gain the Presidency.    The question is, WHAT COMES NEXT?
