Jeb Bush's top adviser, Sally Bradshaw, has left the GOP and will likely vote for Hillary Clinton, which underscores the close friendship between the Bushes and Clintons.

Bradshaw, who served as Bush's senior adviser to his 2016 campaign, claimed Donald Trump is a "bigot" in an interview with CNN.

"Donald Trump cannot be elected president," she said. "As much as I don't want another four years of Obama's policies, I can't look my children in the eye and tell them I voted for Donald Trump."

That's an odd statement considering Obama's drone strikes have killed hundreds – if not thousands – of children in the Middle East, and there's no reason to think Clinton would do any better.

Bradshaw also said Trump's recent spat with Khizr Khan, a Muslim immigrant whose son died fighting in the 2003 invasion of Iraq, is convincing her to back Hillary, which is a weird statement as well: Clinton supported the Iraq war whereas Trump was vocally against it.
