Republicans seem intent on destroying the Republic

Let's be clear, there's a straight line between this:

In a vintage return to his confrontational style, Sen. Ted Cruz indicated that Republicans could seek to block a Democratic president from filling the vacant Supreme Court seat indefinitely.

And this:

Jared Halbrook, 25, of Green Bay, Wis., said that if Mr. Trump lost to Hillary Clinton, which he worried would happen through a stolen election, it could lead to “another Revolutionary War.” 

“People are going to march on the capitols,” said Mr. Halbrook, who works at a call center. “They’re going to do whatever needs to be done to get her out of office, because she does not belong there.” 

“If push comes to shove,” he added, and Mrs. Clinton “has to go by any means necessary, it will be done.”

The connecting line: Conservatives have spent a generation arguing that Democratic governance isn't just wrong, but illegitimate. (Thus the Clinton impeachment, thus birtherism, etc.) If Democratic governance is illegitimate, then of course you block all judicial nominations, of course your partisans warn darkly of an armed revolution if the election doesn't turn out their way. It's an approach that invites disaster. We're about to find out if that disaster is finally at our doorstep.
