I still say that amicable resignation is much more likely than impeachment.
Remember that the GOP is delighted with gutting the EPA, gutting bank regulation, gutting the federal bureaucracy and gutting even the State Dept. This is all stuff their puppeteers wanted to do; they just never dreamt the American public would tolerate such gross malice.
Since this massive sellout to the kleptocracy will not be repealed under a President Pence, what is the incentive for the Democrats to join in a conviction vote in the Senate? Instead, by making a deal with the Devil they might salvage something for the country they’d never get under Pence.
The GOP won’t dare try to impeach Trump.
