Well... in a way Obama did something similar with his "I'll have a lot more flexibility once I'm elected" message to Putin, and while everyone threw a fit, nobody impeached him. One could argue he and those under his direction spied on Trump's campaign and was "digging for dirt on a political opponent" and that he weaponized the DOJ. I guess we'll see if anything happens for that... so far it looks to me like not much ever happens to Dems....
Having said that, I realize I'm looking at this through my own lens. I try to be objective, and I'm open to the possibility he did something wrong, but so far I haven't seen it, and quite frankly after the Mueller probe I'm highly distrustful of anything the left goes after him for. Lots of exaggerating and wishful thinking going on by a lot of elected officials and almost everyone in the media. You can't blame me for being skeptical. I think Trump's gotten shitty treatment compared to other Presidents and I think a lot of what's been done to him would have gotten a lot more pushback from the Media if it were happening to a Democrat.
