One cannot fault your logic. But as a matter of fact, Congress would be under no obligation to proceed with Impeachment, and it is even less likely that the Senate would convict.
It simply does not follow that any finding of the courts, or any criminal indictment ... or even conviction ...would AUTOMATICALLY lead to Impeachment.
Good first step in a very, very long and arduous race.
It was not my intention to imply that impeachment or removal by Senate trial would be “obligated” or “automatic.” However if a president were to be convicted of a felony, it is highly likely that president would be viewed as a liability and a pariah to his own party.
Look at how quickly a Democratic majority got rid of Rod Blagojevich in Illinois last year and it is the Republican majority in South Carolina that is trying to get rid of Mark Sanford. And six out of seventeen Republicans voted to impeach Richard Nixon when the House Judiciary Committee drew up articles of impeachment. Losing those Republican votes is what convinced Nixon to resign because the full House voting the Articles out and a likely conviction by the Senate became a foregone conclusion.
