“Is it possible that they are impeaching Trump because it is the right thing to do?”
No.
Any trial where the decision to press charges was made by long time open enemies and at least 75% the judges needed for conviction are long time open enemies too is never the right thing to do and not being done for an altruistic reasons.
“That for generations to come children should see that actions have ramifications?”
I sure never heard Democrats saying such things when it comes to any other crime. To put it mildly The Democrats are only tough on political crimes like “hate” crimes. And a very specific type of hate crime as well. The ruder murder in places like NY and Chicago almost doubled after the BLM riots and Gorge Floyd “police reform.” But that us a complete non issue for Democrats. If the is murder being done by people who vote Democrat and for the non racial motives which Democrat gives a hoot about black lives then? Let alone “that for generations to come children should see that actions have ramifications”?
