CRAIG MELVIN, MSNBC: The state [Democratic] Party in Georgia using the issue of race to drive African-American turnout there, as you know. Georgia Democratic Party has distributed some fliers warning that if folks don't vote, there will be another Ferguson. In Arkansas, voters also opening mailboxes to images of Ferguson. In North Carolina, Harry Reid's super PAC is running this ad on black radio accusing Thom Tillis of leading an effort to pass kind of gun law that, quote, "caused the shooting death of Trayvon Martin." Is using the issue of race like that to drive turnout, is that appropriate?
