One of Hillary Clinton's best political allies became the Governor of a swing state. Why on Earth wouldn't she consider him a potential veep?
Maybe if he sets the world on fire with his governing, but HRC is probably wise enough to avoid McAuliffe like the plague. He basically got the job by accident - no primary challenges - and still barely managed to eke out a win against the Cooch in extremely favourable conditions to Democrats.
He is also known as a slippy mofo. If the common perception of Hillary is that she's a corrupt Washington insider who relies on an incestuous inner circle, why emphasise these flaws by picking McAuliffe?
