Wrong. More would have been enacted if Congress wasn’t able to buttress the slow walk of the budget, wall, tax policy, health care, etc. They used the allegations as a reason to not do anything and hold Trump hostage.
Not just Congress but also foreign relations. Foreign countries see this nonsense and think they can wait out a distracted POTUS.
Or even worse, they might imagine that he will be impeached, and in the case of a cowardly RINO POTUS they might be right. Good point.
