Really? Like which one? Are you counting Iran?
No. Obama did this. So did Clinton.
No. The S Korean President did this. Trump managed to not completely fuck it up.
That was Congress and also terrible for the health of those markets (and also for health of Americans)
He did deny Federal workers a pay raise, I'll give you that. But whatever savings you can quote are completely blown out by the cuts to revenue.
You can think Obama and Congress circa 2008/9 for that.
You literally could replace him with a cardboard cutout and you'd see the same response. Folks know that the Republican party is in the business of using public resources to make businesses more solvent.
Again, this has nothing to do with Trump.
Disclosure: I've been a registered Republican for the last 18 years.
