I had a discussion with my buddy Fr. Ockham, who advised me as follows:
Impeachment is the process by which a legislative body addresses legal charges against a government official.
Draw strength, we don't know everything we know that Trump won, by a lot. The Politicians know more than the public about the true status of DJ Trump, he is still the legal President, not Biden.
Why else are they going down the impeachment route ?
If DJ Trump was now a civilian, they would be unable to impeach him.
He's already been impeached (while in office), but not convicted.
They want to stick the insurrection charge on him (through political process) due to Section 3 the 14th amendment:
They will never convict him in court, because he is innocent.
But if they convict him in congress they can (try to) point to the 14th amendment and prevent him from running or at least convince the public that it would be unconstitutional for him to run.
It's all very flimsy and manipulative like you would expect from Democrats and Republicans.
