I honestly don't know how it would be likely to go. I can totally imagine people being fired up and wanting to clean things up the only way they can. I can also totally imagine people being overwhelmed with a sense of "nothing matters, he gets away with *everything*" despair.If you don’t like trump, would you be more or less likely to get out and vote if the impeachment vote fails along party lines?
Similarly, I honestly don't know if the folks who are somewhat lukewarm Trump supporters will want to punish the Dems for their perceived overreach or if they'll tune out in disgust. (The Basket of Deplorables™, I assume, will and were always going to turn out and vote for their dear leader no matter what.)
