You are asking for the impossible from one person. I’m not going to spend hours-days looking through every “prominent Democrat”’s public statements and tweets, FB posts, etc. to prove our point.

I could ask the same of you, prove that Democrats as a whole have been specifically targetting Trump. Opposing his and Republican actions are entirely different, of course there has plenty of that from most of the party. A few Democrats out of hundreds speaking out against Trump specifically is not the same either as I mentioned before.

As of November 15th, only 6 House Democrats supported impeachment: http://abcnews.go.com/Politics/democrats-introduce-articles-impeachment-president-trump/story?id=51167864

It’s not that the rest support Trump but they are trying to remain out of the lime light and are hoping the investigation leads to something.
