Those failures should be draped entirely around the necks of the Republicans in Congress. They earned them on merit. The GOP has no interest in repealing Obamacare or protecting our borders.
I believe there were a number of things like this where Republicans held back expecting Trump to not survive. Why didn't Republicans defend Trump over the child separations at the border that happened during the Obama administration? It's not because Republicans would sacrifice children to open borders), it's because they still see Trump as damaged and don't want to be aligned with him.
That's the impact the Mueller investigations are having on Trump, making him toxic to supporters.
