Whatever we do regarding taxes and voting, it will likely require a repeal of the 24th amendment. Those three little words "or other tax" are what turn it evil.
I am betting that it is impossible to repeal the 24th amendment, and any attempt to do so will result in accusations of "racism".
Much like Golum and his ring, I don't see government (both party's) ever giving up it's power to tax. But I can still wish.
