I'm not going to try to change your opinion, but when I see or hear comments like yours, my head spins. Poor performance can mean a lot of things, mostly incompetence. That does not mean malice.

I have observed that the Biden Administration does not want Trump to win in November.
I have observed that the Biden Administration does not care very much about adhering to the law.
I have observed that Trump will win in November unless he is stopped, and — so far — the Biden Administration has been unable to stop him.
I say these people are desperate.
