WATCH: Addled Bill Clinton Sleeps Through Hillary’s Speech

Hillary Clinton made history with last night's speech at the Democratic National Convention — but the buzz was all about Bill Clinton's bizarre behavior. His rambling salute to his wife during the event in Philadelphia was a major embarrassment. Things got worse when Bill fell asleep during Hillary's big moment, as her running mate Tim Kaine desperately tried to hide him from the cameras!

Even as Bill rambled on about Hillary in his own painfully long speech, people were mostly distracted by his shaking hands and quavering voice. Speculation also included talk of possible throat cancer! The National ENQUIRER revealed that Bill was battling Parkinson's disease, but the aspiring First Husband denied it — only saying: “I have a condition that sometimes you get with aging."

Parkinson's disease has been linked to excessive cocaine use, and Hillary's campaign was further rocked when charges of her husband's drug addiction were recently renewed. Insiders have also gone public with their concerns that Bill is suffering brain damage — prompted by several embarrassing appearances on the road to Hillary's nomination!

Longtime fans of Bill were shocked to see the former President looking dazed and confused at a Tucson, Ariz. appearance during a Hillary campaign rally. The formerly vigorous campaigner wandered around a stage while former Congresswoman Gabrielle Giffords and her husband, Mark Kelly, addressed the crowd.

The ENQUIRER also exposed the bizarre scandal where a "dazed" Bill ruined Hillary's Super Tuesday victories by possibly violating election laws! Workers at polling places for the presidential primaries had to be alerted that Hillary's husband was wandering to election sites and making personal appearances. The veteran politician seemed unaware that campaigning isn't allowed close to voting precincts!

“Bill is clearly not the same person he was a year ago, or even six months ago,” a D.C. source told The ENQUIRER. "He is much slower physically, and he suffers periodic mental lapses.”

An article in the Chicago Tribune described how Bill had become flustered while trying to make a point against Hillary's opponent Bernie Sanders. The reporter wrote about Bill first "becoming annoyed" while talking to the audience, and then abruptly and hastily "changing course" while making his speech.

There was another embarrassing gaffe when a cranky Clinton was confronted by a former Marine in South Carolina who demanded answers about Hillary's response to attacks by Libyan terrorists on the American embassy in Benghazi. "Shut up and listen!" shouted the former Commander-in-Chief.

Bill's former close advisor Dick Morris agrees that Bill is fading fast — as The ENQUIRER columnist said: “I didn’t recognize the character that was on TV. He was washed-out, he was listless, he was apathetic — he was very slow-talking, and even slower thinking!”

Calling Clinton’s condition “clearly deteriorated,” one insider told The ENQUIRER that the ex-Prez “has trouble maintaining his balance. It’s just devastating to see him like this!”
