Clinton was investigated and impeached because of the opposition political party. Not for getting a BJ, but for lying under oath. Wasn't smart for the GOP to do then and it blew up in their faces (errr. sts).
Trump is being investigated with his own party controlling the levers of power. Telling how much the establishment on both sides don't want his outsiderness. He's rocking their boat however chaotically he is doing it.
So he's being investigated after firing an executive branch official who serves, like all do, at the pleasure of the President.
An open-ended investigation that has carte blanche to go anywhere, covering any activity, at any time in Trump and his associates lives.
Not sure I could withstand such an open-ended investigation without them finding something or, if not, for 'obstruction of justice' and/or 'lying to federal investigators' when even an "I don't remember" can be indicted as such. Not sure many of us could.
Now national level politics is a dirty business because of the many dollars that can accrue from the activity, but our intel agencies spying on, and revealing to the media, the private conversations of Americans, the leaking of classified information by a SecState/candidate, the head of the FBI, his deputy, the lead CI investigator, etc, etc doesn't bother you, it should.
Or knowingly lying multiple times by lying to a FISA court (itself an aberration of what is supposed to be our open judicial system).
Or the weaponizing of the IRS against political opponents which happened. IRS admitted it and paid millions in fines. That should bother you.
As just a start. And not because Obama and Co. did it. But because it was done and there were no consequences. As least as of to date. What do you think the GOP is likely to do with their power?
And the next guys?
Each time, the boundary will be pushed just a little further because the likelihood of negative repercussions to those misusing the powers of the federal government grows smaller each time.
Yes, I do want you to get off my lawn, but more importantly, I want you to get off of my Constitution.
