In my area, Democrats campaigned on the fact that the GOP has had full control of the Federal government for two years and has accomplished almost nothing. I voted a straight Republican ticket for the first time in my life, but I couldn’t argue with that.
The GOP was too busy fighting Trump.
On the lack of action by the Republicans in” full control of the govt.”, you could also say that the Democrats had the same control and didn’t get anything except Obamacare by a very skinny margin and deceit. Seems to me apart from favorable judicial rulings, bureaucratic rules and executive action, the government doesn’t work too well legislatively.
