Lately, the Voting Rights Act has gotten a lot of attention. Some seem to think that when (if) it expires, we'll suddenly be flung back to the days when blacks couldn't vote. People forget that it is merely an enforcement act to supplement the 15th Amendment. "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude." The only reason the Act was introduced was to enforce the 15th Amendment (as allowed by section 2 of the amendment), and I would hope that we have passed the days in which such enforcement was necessary. No one questions a person's right to vote based on race, Act or no Act.
If you disagree with me, the act may still be necessary...though I would guess that there's not a state in the Union that would dare infringe someone's right to vote based on race.
