We're too polarized for anyone to win in a landslide. However, I think this matter ultimately helps Trump in two ways. First, the Democrats did a crappy job and will obviously fail. The vote was their pinnacle. It's all downhill from here. And frankly, it wouldn't surprise me if some Democratic senators (Doug Jones, Joe Manchin, and perhaps Kirsten Synema) vote to acquit if the matter ever gets to them.
Second, the impeachment process damaged Joe Biden more than anything Ukraine could have done to him. The reason why is that Joe Biden was largely considered at least by many to be a decent guy before this. Now he looks like a sleazy guy.
So instead of 2020 being "Good Old Joe v. Sleazy Trump," it is now "Sleazy Joe v. Sleazy Trump."
