Josh Barro: Why I Left The Republican Party To Become A Democrat

Barro:

The most important thing we have learned this year is that when the Republican Party was hijacked by a dangerous fascist who threatens to destroy the institutions that make America great and free, most Republicans up and down the organizational chart stood behind him and insisted he ought to be president.
Some did this because they are fools who do not understand why Trump is dangerous.
Some did it because they were naïve enough to believe he could be controlled and manipulated into implementing a normal Republican agenda.
Of course, there were the minority of Republicans who did what was right and withheld their support from Trump: people like Gov. John Kasich of Ohio, Sen. Ben Sasse of Nebraska, and Hewlett-Packard CEO and megadonor Meg Whitman, with her calling Trump "a threat to the survival of the republic."
I want to focus on a fourth group: Republican politicians who understand exactly how dangerous Donald Trump is but who have chosen to support him anyway for reasons of strategy, careerism, or cowardice.

   Rubio, Cruz and Ryan in particular...
