Since the violent insurrection at the Capitol was overcome, a number of Republican officials have denounced the wrecker and his coup attempt. Some have, it seems, dropped their support for their part in it.

Ilhan Omar is preparing to impeach the wrecker again. I share her disgust for him, but would this do any good?

The first impeachment was ineffective because the Republicans in the Senate protected him. Is it worth trying again? Perhaps now enough Republican senators are ready to remove him from office. If not, some Republican support for impeachment — if there is any — might educate Republicans.

However, bad results are also possible. Firstly, it would not affect any of the sabotage that Republicans will continue doing until Jan 20. Pence would continue those efforts.

Secondly, if Pence becomes president he might pardon the wrecker.

Indeed, I've seen speculation that the wrecker might resign so that Pence can pardon him. But I don't know if he could bear the humiliation of leaving office early.
