This whole argument about Hillary Clinton's health is pretty ridiculous, especially the parts where her foes are believing and spreading stories of what's "really" wrong with her that obviously did not come from anyone in a position to know. But as Eric Levitz points out, it's really a non-issue because no one who was going to vote for her or not vote for her is likely to change that vote even if she is gravely ill. (And of course, there's no actual evidence that she is.)
