I'm going to say the lies about Vietnam, Watergate, Iran-Contra, and so on did more to set up Trump than Clinton, but people who think Reagan was a good POTUS need a good lie to sell themselves.

The reality is, the back-to-back of Dubya & Obama were probably the longest stretch of personally moral adult lives of President's in history by modern standards. Add in Biden, and ignore Trump and America actually has a decent record, putting aside terrible policy decisions, outside of the blinking orange wrong decision
