The key difference here is this:
1. Obama was doing it in the name of national security and wasn't trying to gain a PERSONAL benefit.
2. Trump was trying to get a personal, political "favor".
Using the office of the President for personal favors is illegal when dealing with other nations.
This is called abuse of power.
Only if you decide it was a personal favor, and not investingating corruption.
That is the crux of the entire thing.
I posted this before all the hearings began, and nothing has changed.
The trouble is, the impeachment inquiry did not prove any of this with direct evidence, just heresay and conjecture. How many clips of the witnesses admitting this do we have to see?
You, like many other Democrats, had your minds made up before the inquiry.
Republicans did too, but the burden of proof is on the accuser, and the accuser failed.
