This is, of course, taking only the nominee of a party into consideration and taking Toni Morrison's assertion that Bill Clinton was the "first black President" at face value. Otherwise there are lots of failed black candidates - Jesse Jackson, Ben Carson, Herman Cain, Alan Keyes etc., though there are more Catholics too (Biden, Eugene McCarthy, Ted Kennedy, Pat Buchanan, Rubio, Jeb!, Rudy Giuliani, Alan Keyes (a twofor!!! - he's also black), Santorum, Chris Christie, etc.).
ἡ δὲ κἀκ τριῶν τρυπημάτων ἐργαζομένη ἐνεκάλει τῇ φύσει, δυσφορουμένη, ὅτι δὴ μὴ καὶ τοὺς τιτθοὺς αὐτῇ εὐρύτερον ἢ νῦν εἰσι τρυπώη, ὅπως καὶ ἄλλην ἐνταῦθα μίξιν ἐπιτεχνᾶσθαι δυνατὴ εἴη. – Procopius
