i'm not going to dwell on this, but let's be clear.
1) there's clearly an issue of some sort. i see no evidence of any specific diagnosis, like parkinson's. but, the clinton campaign has not provided a good explanation for any of the unusual images or videos that have surfaced. while we should all realize that we are not doctors and should not diagnose at a distance, we should also realize that the evidence before us requires some explanation that has not surfaced.
2) clinton cannot rely on 'trust us'. she's a known liar. only the very core of her base will accept this. the left will not. the right will not. the swing in the middle will not.
she may have dug herself into a hole. the clintons are experts at hole-digging, after all. but, she needs to be more clear about what's happening. if it turns out that all that's happening is that she's a 70 year old woman in terrible shape, so be it. but, she'll have to own up to it rather than continue to deny it.
it could be a real factor in terms of creating voter apathy. but, what can i say? she's obviously not very healthy....
