I agree; the mainstream media are vile--but I'm not sure that there's a reaction that couldn't be spun. If people applauded, then "Those nasty Republicans applauded--they're glad that Clinton has heart problems!" We've already seen the response to the (false) claim that they booed. If they were silent, then the media would say they were "displaying the callous indifference that Republicans display in their domestic and economic policies."
Ain't that the truth.
