As HRC was a very unpopular candidate, someone slightly more popular than her could have won the election. A lot of her unpopularity came from years of GOP slanders, and I'm not convinced that would have stuck on Al Gore the same way. I think he wins, but the GOP keeps congress, preventing him from any major accomplishments legislatively. Reasonable to assume he loses in 2020 to another R-candidate. So basically a 1988-1992 redux.
