I don’t think so, because there is no doubt that Trump will be exonerated; will not be removed from office.
Senator Edmund Ross was in the book “Profiles in Courage”, because his was the deciding vote to acquit President Andrew Johnson in his impeachment trial, and he was subject to immense political pressures as a result.
In this case, even if a few Democrats cross over and vote to acquit Trump, I don’t think their actions will be considered historic.
I didn’t click all the way through the last time the topic came up.

I did look up that Ben Wade was President Pro Tempore but somehow I wrongly remembered that he voted not guilty. But according to Wikipedia he voted guilty.

I assume Ross had announced intentions to vote guilty then changed at the last minute?
They do the roll call alphabetically, no? The final Republican vote to acquit was Peter Van Winkle (WV) and the final Democrat vote to acquit was George Vickers (MD).
