You had at least two how does that factor into a decision about whether to run for president and all the flying that that entails . It doesnt factor in at all. I have no doubt that im healthy enough.

Donald, dream on. Clintons campaign struck backt Donald Trumps report. A brief letter praising Trumps Health as astonishingly excellent, extraordinary. The letter addressed to whom my concern.

Clinton may have to leave the trail for a little bit. How much impact could this have and question should the campaign have told the public on friday that she had pneumonia . Second question first, yes. 100 yes the campaign should have done that and disclosed and perhaps they didnt because they fear the innuendo campaign thats been going on on the far, far right corners of the internet. But that was a mistake. Makes it look like a coverup and only feed more questions and allows that to get mainstream. That was a mistake. I think what youre going to see over the next week is a focus on the fact that both of these candidates for president , if they among the oldest people to ever serve as president. Donald trump would be the oldest elected to a first term. Hillary clinton would be the second oldest. We dont have their full medical records.
