Not to go all Willco on yall but I'm noticing some rather asinine identity politicking from both sides. From Brian Beutler's hand wringing over whether Hillary is too white for black people to the emerging consevative consensus that Rubio holds the key to the Hispanic vote.
Real talk: black demographic gains ensure the 2016 electorate will remain about 12-13%, and anyone hand wringing over it returning to 2004 levels is wrong. And even if Rubio is on the GOP ticket (top or bottom) he's not going to convince Hispanics to suddenly adopt positions they disagree with (anti-immigration, pro life, no government involvement in the economy, etc).
