I don't know one thing about Hillary Clinton's health, but I do know this:

Say one thing about it, and her protectors will get really nasty.

Case in point: Rudy Giuliani. Says The Hill:

Donald Trump adviser Rudy Giuliani pushed the idea that Hillary Clinton has health issues by telling viewers of "Fox News Sunday" they should Google "Hillary Clinton illness" and watch the videos that pop up.

Giuliani claimed the media "fails to point out several signs of illness by her. All you've got to do is go online," he said Sunday. 

"Go online and put down 'Hillary Clinton illness,' take a look at the videos for yourself," he said. 

So we get this from the Clinton campaign:

Clinton campaign press secretary Brian Fallon responded Sunday, saying: "Google Rudy and health and you can read about how he withdrew from '00 Senate race against Clinton," he tweeted, referencing Giuliani's battle with prostate cancer.

Nice! Actually, we all know that Rudy battled prostrate cancer.

Earlier, Trump said this (according to Washington Post columnist Ruth Marcus):

“To defeat crime and radical Islamic terrorism in our country, to win trade in our country, you need tremendous physical and mental strength and stamina,” he said in Wisconsin. “Hillary Clinton doesn’t have that strength and stamina.”

Marcus's reaction:

It’s obvious what’s going on here. The strength-stamina combo is a gender-age twofer, a double whack at Clinton for the price of one. Strength, what men have and women lack; stamina, with its intimations of go-all-night virility. Clinton, in this depiction, is both a weak girl and a dried-up old crone.

Ageism and sexism! Intersectionality!

And then there's this, from Laurel Raymond of Think Progress:

As Trump’s campaign has fallen further and further behind, the conspiracy started to show up again on right-wing websites. Matt Drudge and Glenn Beck’s The Blaze circulated a months-old photo of Hillary Clinton being helped up stairs. Widely-debunked blogger Jim Hoft wrote on Instapundit that “exhausted Hillary is taking weekends off.” Pro-masculinity activist Michael Cernovich wrote that “Sick Hillary can’t stand up on her own, had hidden stool behind to keep her held up,” and that Clinton appears to travel with a “handler” who helps with her frequent “seizures.” 9/11 Truther site InfoWars posted an interview with “Pharma Bro” Martin Shkreli in which he diagnosed Clinton as having Parkinson’s. Days before its chairman became Trump campaign CEO, Breitbart.com published a story about a Tea Party-linked doctor who had not treated Clinton but claimed she appeared to have some signs that could indicate “traumatic brain injury.” Even Dick Morris got into the act, asserting that there are “all kinds of indications of health problems” and that Clinton “looks horrible.”

So OK, I get it: If I say one thing about Hillary Clinton's health, I'll be accused of ageism, sexism, being "pro-masculinity," having links to the Tea Party, and wearing a tinfoil hat. Plus, Brian Fallon will dig up every illness I've had since my bout with the measles at age 10.

So I promise: I won't say anything about Hillary's health! Ever! Cross my heart!
