Zero, and they know it. Where were useful Bills when we had the House, Senate, and Presidency?
Reactive, not proactive.
When they had all the power, it was more fun to stoke the Ukraine war, utterly drag their feet on the wall, fully support and fund Mueller, pretend Trump was a Russian asset, undermine him in Korea, save Obama care, supporte more China trade for corporate buddies, impede the wall, debase the military with degenerates, and pass omnibus spending bills rather than a defense bill, an agriculture bill, etc… one by one with no amendments. They did nothing about election fraud. And knowing for a fact the FBI protected Hillary and tried to frame Trump. they rewarded them with a new multi-billion dollar HQ building. They rewarded the CIA with the Patriot act renewed and expanded.
Screw the republicans.
With the smallest support from his own party, god only knows what Trump could have done.
