In context of the claim dejudge was replying to, I don't think he was saying that the first impeachment helped the Dems to victory in 2020 so much as that it didn't hurt them nearly as badly as people were afraid it might.
Agreed.
The Atheist said that impeachment would "harden voters' opposition", and dejudge said that the claim had been refuted.
I don't think the Atheist's claim that a second impeachment would harden voters' opposition was refuted by the fact that Donald Trump lost re-election after the first impeachment.
That much should be blindingly obvious to everyone. Obviously, what happened last time cannot prove anything about what would happen if we do something similar again. Furthermore, the fact that something occurred after the last impeachment can't even be tied in a causal manner to the subsequent election results. We cannot tell whether Donald Trump got more votes or fewer votes as a result of impeachment.
What can be said with certainty is that impeaching Donald Trump did not cause him to be re-elected. We know that because Donald Trump was not re-elected. The above are all things that cannot be disputed by anyone who can read.
It is my opinion, which I cannot prove, for exactly the reasons mentioned before, that the first impeachment of Donald Trump caused him to get more votes than he otherwise would have.
Did I mention that can't be proved? So, if anyone feels like posting, "You can't prove that." feel free, but know that I'm already saying that. Right? Can't prove it. Right there on the page. My opinion.
It is also my opinion that the Atheist was correct. My belief is that a second impeachment would harden opposition to the Democrats. I will amend that somewhat, though, by saying it would only do so if they failed to convict. However, as I stated earlier, I'm not sure I care. Impeachment and removal from office is the right thing to do, so right at this moment I'm leaning toward saying they should do the right thing, regardless of political calculations.
