What would it take?

If Trump's executive order, any of them, were blatantly unconstitutional, then Yates would have been in the right to not defend them in court, and she still likely would have been fired.

But

Trump's order is not unconstitutional - it is not a ban of all Muslims, it is not infringing on the rights of any US naturalized or native born citizen, it does not deny freedom of religious expression or free speech (heck it clearly gives opponents more opportunities to use that valued right), and it is based on existing law that has been used more selectively for the same principle.

We will quickly see how deep Trump's support goes. Clearly the activist base of the Democratic party is energized and out in full force. If Trump's support is broad enough to force the Republican party to stay the course, then these protests could be the last gasp of a dying democratic resistance. If the Republican's in the Senate don't stand with Trump's "movement" then it will flame out, and Trump will be a one term lame duck president.

We seem to be living through a defining epochal in our history.
