Well, vote for somebody else. That’s what most people do. Passing a law barring people from running for office puts the power in the rino party leadership.
This is not an unreasonable requirement in establishing a residency for 3 years. Given the fact that it’s not unusual for a candidate to get a very low percent and win because we have no runoffs (which has resulted in many many RINOs getting in, as they divide the Conservative vote), this can at least weed out people who decided to move in last week, and jump into the fray with no previous participation in local politics.
