Abso-fucking-lutely nothing to do with auto racing, or anything else some functionally illiterate hillbilly might suggest. Popular usage of the phrase pre-dates that example by many decades. It's rooted in baseball, refers to leagues considered to be inferior to the majors, and is purely coincidental that it shares a spelling with our 43rd President.

6.
A phrase commonly used in (but not restricted to) baseball to describe something (usually a playing style or attitude) that is not respectable or sportsmanlike, but technically not breaking any rules of the game. Someone who commonly plays with antics that are considered bushleague, would be considered a "bushleaguer". Both "bushleague" and "bushleaguer" can also be used to describe unsportsmanlike acts by fans, and to describe the fans themselves, respectively.
