Actually I supported him as he was the only hope for the "ordinary bloke" against the, IMO, monster that Washington has become.
If one goes back 6 or 7 years I said on the forum ( TVF back then ) that I'd support a rock if it defeated her. I'm not a fan of millionaires, but the "enemy of my enemy is my friend" is relevant with Trump. I'd have preferred Bernie, as he was openly against Wall Street, but IMO he was sabotaged by the Democrats.
Yes, Trump was being attacked on all fronts both by the Dems and by enemies in the GOP, so I saw him as the underdog.
Certainly millions and millions of Americans think Washington is a "swamp". Are they all wrong?
The bigger picture is there has been no POTUS in living memory who has tried more to undermine democracy than the Orange One and this alone should be the only reason you should choose to not support him.
Given my opinion of politics today, that is reason enough to support anyone that goes against the establishment.
