I wish I could take credit for it but it was a meme going around the blogs at the time. The best part of that slogan would have been how much it would p*** off racists. The song "Sweet Home Alabama" is actually a song celebrating racism using not so subtle dogwhistles. So coopting it for a Democratic campaign with a black guy on the ticket would have infuriated rednecks. But hey, if Ronald Reagan can use Springsteen's "Born in the USA" as a campaign theme without permission than simply using a song title soundalike minus the song wouldn't be unprecedented.
