Let's cut a deal: automatic voter registration if voters pass a civics exam over the US Constitution
The tests can be free. Hell they can even be delivered verbally to avoid the whole literacy test connotation.
I would feel a lot better knowing that every voter had sufficient knowledge about concepts like federalism, separation of powers, limited government, pluralism, etc.
Democrats would never agree. They'd label it racist because they know a good quarter of their voters have to be bribed in the final hours of the election just to vote
Testing like that would be beneficial to voters if the candidates had to answer.
