Apparently Atwater feared Clinton as the greatest threat to Bush's re-election, so he'd do his utmost to sabotage Clinton during the primaries and after that the general election (if he makes it that far). But given that Clinton's baggage was already in public view when he ran and was the subject of fierce attack campaigns but still won nonetheless I think Clinton would've won with or without Atwater. Perhaps it's fitting that Atwater's death ultimately had little to no impact on human history - he was nothing more than a parasitic, ruthless and cruel man who lived for nothing other than political victory at the expense of other people's lives.
