Yes I do, I think Trump would do anything to discredit anyone who runs against him, absolutely. And again, the timing is suspect. Why wasn't Trump concerned about this corruption in 2016, 2017 or 2018?
I don't know who the democratic choice will be and frankly don't care because I certainly don't see one among them (sadly) who could defeat Trump. What I am concerned about is another 4 years of this buffoon in office.

Trump doesn't appear to be losing much in his national rating, maintaining a fairly steady course!
