Maybe he’s warning the media.
Could be that he is warning the rest of the media. Until Obama, the Dim strategy to win the white has has been to nominate some southerner, LBJ, Carter, Clinton, who could attract a few extra low information voters who would still believe a southern Dim is conservative. Obama showed that they could also win by nominated a black candidate and win on increased black turnout.
Do they have a southern candidate for 2016? A black candidate? Will a women candidate increase female turnout and work the same for them as Obama did in 2008?
