We are already in a constitutional crisis..
Nanzi is working to sustain the constitutional crisis which peaked when DJT was inaugurated and has been receding ever since. The crisis would have grown exponentially if Hillary had stolen the election as she did the Demo nomination.But it was not a foregone conclusion that Obama would actually step aside, so Trumps inauguration marked the peak of danger.
Nixon was forced to step down, but Clinton walked even though he was guilty as sin - and Barak Obamas Justice(!) Department spied on a presidential candidate like Nixon could only have dreamed of. Republicans know it. If Nanzi thinks that Trump can be impeached and convicted without a real constitutional crisis, she has no realizing sense at all.
...and have been since at least 2008.
