I think wherever you stand on the left vs. right spectrum, it's clear now that "High crimes and misdemeanors" is now de facto defined only as "stuff we don't like that the other party's guy did." Trump could openly commit treason and probably not even be impeached ny his party, let alone removed.

But I don't for a second believe that the Democratic Party would cooperate with "their" person being impeached now either, except if it was politically advantageous for them (for instance, to remove an unpopular Democrat for an embarrassing misstep when there was a popular VP ready to go). No way would they impeach for crimes of overstepping presidential authority to do something the President from The West Wing would be proud of, for instance.
