Another article on this subject had this sentence in it:
The Tennessee Republican Party’s bylaws require, among other conditions, that candidates have voted in three of the last four GOP statewide primaries in the county of residence, and are actively involved in Tennessee or county Republican parties.
The worrisome part is ...."AND are actively involved in Tennessee or county Republican parties."
That would seem to disqualify anyone who has never been in politics before no matter whether they're natives or not. No angry citizens...only experienced GOP party people can run.
It could also mean an active donor as well.
It could also mean a precinct poll worker or put signs in yards. Or make campaign phone calls for other candidates. Active can mean a lot of different things. I see nothing wrong with that.
