Does Hillary Clinton have serious health problems that she's hiding from the public?

You are behind in the news. This has been around for weeks.

1. This is a conspiracy theory concocted by the Republican campaign to attack Hillary.
2. She already responded to it and had her doctor confirm she is in good health.

Donald Trump's gastroenterologist says so.  It must be true. 

Not any which would disqualify her from holding office.

She needs to go back for an MK Ultra refresher.

Other than Bill? Not that I know of. Lacking honesty and integrity isn't a health concern

I doubt it.  I think that's just the latest GOP chew toy.  Republicans know that Trump is going to fail miserably at the debates so they're pushing all the conspiracy theories they can.  That's what happens when a political party realizes their candidate is an epic failure. 

Wouldn't that be kind of stupid.  What is the point of running if you are sick?

Both sides say the other candidate has health problems, though Hillary's light schedule and some pictures and videos appear to indicate there may be a problem. Personally, I'd love to see BOTH CANDIDATES have a thorough medical examination (similar to the annual exam the President gets) by impartial doctors - or at least equal number from both parties. We have the right to know if they are medically, physically and mentally up to the job.
