I gave him the last word about "racist voter ID laws".
Not even worth opening that can of worms in 140 character bursts.
But, as I'm sure everyone here agrees, I fail to see how requiring people who show up at the polls to prove they are who they say they are (i.e. an actual registered voter, of voting age, or even a citizen of the US) is inherently racist.
I'm sure he disagrees.
