This likely isn't true, but it's fun to think about:
1989, Nolan re-signs in Houston for a couple more years. Rangers don't sign him, and don't have the 16 wins he gave them, finishing sixth in the AL West instead of fourth. George W. Bush & co. don't buy the team, instead opting to buy the Astros several years later. WIthout Dubya's group, the Rangers fail to secure a new stadium contract from Arlington and move to Tampa in 1992. Bush never fires Gerry, but also never runs for governor, becoming commissioner of baseball in 2001 after Bud Selig is mysteriously fucked to death by rabid hyenas.
