Completely disagree.
Impeachment is not some super dangerous procedure and the POTUS is not a person or position that must be protected at all costs. The POTUS is a glorified bureaucrat with a ton of hype. It's 99% hype. After a president is impeached and removed, the vice-president simply steps in, who has pretty much the same politics and policy.
Pulling off impeachment is hard by design and lawmakers will NOT fall in love with it. In a democracy if the votes are there to fire a POTUS from his job, then that tells you he wasn't doing the job properly. The reason it hasn't happened often is simply because it's rare that a President gets so sideways of his job and his lawmakers.
Clinton should have been disciplined but he should not have been impeached, as the majority of people knew at the time. The fact that this Pres has been impeached twice tells you how bad he is.
Give the American people a little more credit. Some will bitch and moan but that's normal.
