Global warming is to blame. In all seriousness, while I have stayed away from commenting on this issue, the time has come for the media to start pressing for further detail. Clearly she is in poor health. Circling the wagons to protect her e-mail scandal is one thing, not investigating a person running for president that can't stand or walk without assistance on what are now numerous occasions...,the people of this country need to know what her health problems really are, and if those problems will affect her ability to do this very demanding and stressful job. This has become a high priority story. The facts need to come out and they need to come out ASAP.
