Many of you know that I'm not Hillary Clinton's biggest fan.

But I would never question whether she was right in the head. Instead, what bothers me is that dark, crusty clump of carbon that some may confuse with a soul.

Before crazed hordes of Benghazi Deniers (in and out of journalism) shout me down with angry cries of "What difference, at this point, does it make?" let's stipulate something:

Karl Rove, the Rasputin of the establishment GOP, has played another dirty trick. This time the target is Hillary, and this one is beneath contempt, even for Rove.

He suggested Mrs. Clinton has suffered brain damage.

And for that he should make a full and public apology.

Rove, like most establishment GOP attack dogs, is more worried about tea party conservatives than Democrats. But his attack on Clinton shows how low he can go.

According to the New York Post, Rove is trying to take political advantage of the former secretary of state's blood clot in 2012, hinting that she suffered brain damage.

"Thirty days in the hospital?" Rove was quoted as saying the other day. "And when she reappears, she's wearing glasses that are only for people who have traumatic brain injury? We need to know what's up with that."

On Tuesday, Rove stammered through an attempt to clarify his remarks.

"Wait a minute -- no, no -- I didn't say she had brain damage. She had a serious health episode," Rove told Fox News. "My point was that Hillary Clinton wants to run for president, but she would not be human if this didn't enter in as a consideration."

"And my other point is, this will be an issue in the 2016 race, whether she likes it or not."

And here's my point, Karl, whether you like it or not.

You're a weasel.

Clinton did take ill in 2012. And there have been responsible questions as to her health and age, given that she's an unannounced 2016 presidential candidate and is considered by Democrats to be Hillary the Inevitable.

But the way Rove played this has me wondering:

Does Rove have a brain? Or is that just a bloodless spider running around in there behind those twitchy eyes?

The grown-up way to answer a question about Mrs. Clinton's health was demonstrated by Lynne Cheney, the wife of former Vice President Dick Cheney.

I asked Cheney about Rove's brain-play when she was a guest on my WLS-AM radio program Tuesday to talk about her new book on James Madison, fourth president of the United States, who helped craft the Constitution.
