Agree with you, anon.
But just had a thought…since this "investigation" seems to focus mostly on what Biden did as VP, what if they were to impeach him as the former VP? Since he's not VP anymore, the Senate wouldn't be able to remove him from VP on conviction, but they could disqualify him from holding any federal office. The precedent's already set by the 2nd DJT impeachment, which happened after his term had already ended; but Pelosi pushed it forward to try to get Trump disqualified from office.
Could this be a way for the House to impeach and Senate convict/disqualify without legitimizing the fake presidency? And then if the Senate disqualified, would that nullify the fake presidency b/c Biden would be ineligible? (I don't have any expectation this would happen, just a thought exercise)
Article I, Section 3, Clause 7 of the Constitution:
Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.
