Why are you bullish on an unpopular ex-president returning to office?
American history is a story of maybe a dozen great men (hopefully women soon, too). Like him or not, Trump is one of those great men that has defined our history - for better or for worse. His story isn't over.
Yes, defined our history by sending a mob on the Capitol and spreading misinformation about the election, he's better than the 1850s era disasters, but other than, it's hard to find a President worse than him.
George W. Bush actually was somewhat tolerable outside of foreign policy and some of his domestic policies. He is ranked similar to Jimmy Carter IMO.
