So, your argument now is "if we can get away with it, then it is okay to do it."
What is Trump getting away with? He is doing things that IN ADVANCE Democrats say will get him impeached. If so, let it happen.
All out in the open
No, he did things that as they become known prompt congessmen(not just Democrats, despite your spin efforts) to say may merit impeachment and removal from office.
Though I suppose it is true that when he asked for China's help that he
was doing a thing that he'd already been told was impeachable.
What he is getting away with, thus far, includes his shameful treatment of the Kurds, his soliciting a foreign nation to dig for dirt in trade for a meeting with him (and perhaps having the release of money they were promised). He's getting away with taking foreign countries' money and filling his own pockets that way.
He's gotten away with filing intentionally falsified data on his buildings for both tax purposes and loan purposes.
Got enough yet?
