At this point, Kasich and Carson are vanity projects. They have no shot at the nomination.
Jeb Bush had the class and good grace to leave the race. Kasich and Carson are proving themselves to lack class.
We know that Kasich’s and Carson’s voters do not got to Trump. Kasich’s would go to Rubio’s or Hillary Clinton. Carson’s go to Cruz and Rubio.
The longer they stay in, their committed partisans are doing nothing so much as assisting Donald Trump.
Kasich has always been a vanity play. He wants clout come convention time. After his performance in South Carolina, it is more and more obvious the Kasich campaign is not about winning, just about Kasich.
