There's a lot to unpack there, some of it beyond my knowledge. However, I will look at this:
First, the GAO has definitively affirmed that the President and the OMB (an executive agency branch) withheld aid illegally, and that to be legal the President would have had to officially follow certain procedures and disclosures as to the reason for withholding the aid--which obviously never happened.

Second, you can look at the "transcript" of the call between Trump and the Ukranian President. (https://www.whitehouse.gov/wp-content/uploads/2019/09/Unclassified09.2019.pdf) In it, there was the classic and well-known point where the Ukranian President asks about purchases of Javelin missiles and POTUS replies with "I'd like you to do us a favor, though". The immediate ask was to have them investigate Ukranian interference in the election, which was a sort of fever dream considering it was Russia, not Ukraine, that did so.
But the very next statements were the Ukrainian President talking about how he viewed the US as a "strategic partnership" and then assured POTUS that all the investigations would be done "open and candididly". The very next statement by POTUS was directly about the prosecutor and Biden's son. And said "Biden went around bragging that he stopped the prosecution so if you can look into that..."
The call between POTUS and Ukraine was July 25, 2019. The decision by the OMB to withhold the duly approved aid was July 25, 2019.
Isn't that... convenient?
So let’s agree on something for the sake of argument because I do not mean to defend POTUS in this. Although asking for a personal favor and using the actual words he used I think it’s a stretch to say it’s anything more than him being an asshole.
but for the sake of conversation lets say I’m wrong about that and that is illegal and he should have been impeached. Is it because, as everyone who was in favor of impeachment claimed, that he used his position of authority to go after a potential political opponent?
if yes, how much did he spend? How much did he hide?
now that has been established factually that the FISA documents were falsely and unconstitutionally and illegally used as the start to the entire Russian collusion investigation, as well as numerous high-level Democrats knowing about it, and several other illegal activities including using false information that they knew was false, is this not the same thing only on a much bigger scale? This one cost $32 million in two years of divisiveness.
That’s what I don’t get. The same people who want to throw Trump in the fire over doing that will sit here and defend the incredibly illegal and immoral activities going on in the intelligence community and the FBI that were used to start the Russia investigation.
