George W. Bush flew F-102s for the Texas Air National Guard historically, and volunteered to fly in Vietnam, but was declined.
Suppose, though, he chose a different fighter, the F-100D Super Sabre? Assume his request to serve in Vietnam is granted, and he serves two tours flying the F-100.
Assume the rest of his life is still similar to OTL... but how does it change the 2000 presidential race?
