THE BEST WAY TO HONOR MLK: Pass federal voting rights laws (and never need to vote again).

Instead pass a two-part voting responsibility act. Part one, proof of identity to enter the in-person voting booth. And part two, proof of civic responsibility, by which I mean understanding the civic responsibility of a citizen of the United States, after entering the voting booth.

For the latter, since civics is no longer taught in public schools, I'd suggest something similar to citizenship tests required for newly naturalized citizens, or drivers licensing exams. Provide a publicly available civics database of multiple-choice questions, one of which must be answered as part of the ballot and counted as part of the ballot. If the answer is correct, the ballot is counted; if not, it is not counted and discarded -- no do-overs allowed.
