Don't expect the 2016 presidential campaign to turn all soft and fuzzy: Republican nominee Donald Trump warned in a tweet on Tuesday that "the shackles have been taken off me," a thinly veiled threat suggesting that the final 28 days of the presidential race will be filled with personal attacks. He then proceeded to unleash a series of tweets against his the GOP, including "Our very weak and ineffective leader" House Speaker Paul Ryan and "the very foul mouthed" Arizona Sen. John McCain. Oh, and the Trump campaign also rolled out a new ad targeting Hillary Clinton’s health.

Clinton’s health — which has long been the subject of right-wing conspiracy theories — was put into stark relief on Sept. 11, 2016, when she abruptly departed a 9/11 memorial service at Ground Zero and video emerged of her stumbling and needing to be helped by aides into her van. Her campaign later said she had pneumonia. Trump also threatened that if more reports about his past surface, he will launch more attacks against former President Bill Clinton for his marital indiscretions.
