John,
Trump's first Secretary of State described him accurately as a moron -- someone who doesn't know and has no interest po desire to.
Nothing much can change who Donald Trump is, but his enablers may be challenged. The likes of Marco Rubio and Lindsey Graham have rendered themselves non-entities, but others from the GOP could be emboldened to stop the Trump buffoonery.
It would help if Democrats had a plan beyond their tired rhetoric.
