If that's what happens, so be it. What I can't handle is the Dems going down without a fight. This is an existential threat to our nation. Either a president is above the law and unrestrained from committing acts of criminality and corruption or he/she isn't. Either a president may betray our nation to a foreign country when backed by a vocal minority of traitors or he may not. Either a president may abuse the power of his office against his rivals in an election or he may not.
There are many Republicans using every stretch of logic they can find to defend Trump, and plenty of Dems pointing out that they would have reacted differently if Obama did it. But if you are supporting Trump in this, the question you need to ask yourself is, am I okay with the precedent I am setting? If AOC becomes president a decade from now, am I okay with the notion that it will be entirely legal and unimpeachable for her to hold up military aid to a country and then say, "I have a favor, though," when the leader of that country brings up aid, and that favor is starting a criminal investigation into the GOP front-runner in the next election? Am I okay with her getting elected in the first place by welcoming help from an enemy nation to hack various aspects of our election system and then, in the Oval Office after winning, telling the enemy's leader that she has no problem with what they did, and then doing everything she can to help them do it again? Am I okay with her covering up this wrongdoing by hiding transcripts of the conversations? Am I okay with this being the new norm?
If you wouldn't be okay with that, you need to question what the hell you are doing supporting Trump now. Because this is where the precedent is being decided. Here and now.
