Hold on, think about that from the other end. Imagine that there was a someone in the WH that was doing some bad things, but they set it up so that an impeachment against them would fail because of some sort of forethought they gave it. With what you're saying, now the people bringing impeachment against this legitimately bad person are not only unable to find another way, but they're getting punished for not being able to prove their case sufficiently? That all sounds like a really bad idea. I'd rather not turn into Iran, thank you.
