The states are often beholden to the Federal government for funds. Rightly or wrongly, the Federal government tied receipt of many Federal highway funds to the increasing the state drinking age to 21. That would be something - a state saying that they will forgo those portions of funds for a larger issue.
One of my themes included in recovery of our Free Constitutional Republic.
States must assert their constitutional sovereignty and STOP FEDERAL FUNDING.
Has to happen. As you suggest, going to take governors who care about freedom and America than their own short-term pollical future.
