I confess that I have almost a “meh” attitude about the Hillary health thing. But the reason is that if it is as bad as it appears to be, it will get exponentially worse between now and the election to the point that either all doubt will be removed, even to the most deluded, or she’ll be dead.
Nothing stays the same. She will not just keep having these “interesting” events. They will continue to increase, exponentially so, as the election approaches.
You get too close to the election before the truth comes out and hillary’s vote is already padded by early voting and write-in ballots. That could be “buyer’s remorse” votes that could’ve gone to Trump.
