I remember him riding a huge wave of popularity after Desert Storm, with approval ratings over 90%.
Then the 1990 backstabbing budget deal (with the large tax increase) came hack to haunt him in the 1992 elections.
One good result of Bush’s high popularity after Desert Storm was that Thurgood Marshall decided to retire from the Supreme Court and Bush chose Clarence Thomas as his replacement. If Marshall had remained on the court until his death, Clinton would have replaced him with an ultra-liberal. Probably Marshall assumed that Bush was going to be re-elected in 1992.
