As the oldest, kvetchiest and least unlikeable member of the militant black KKK, U.S. Rep. Maxine Waters, professional racist, deserves every overripe tomato verbal that is aimed at her always-open mouth.

She must have bought a tall bottle of Incurable Anger the day after she was born, and she has been gargling the odiferous stuff ever since.

She surely holds the all-time record for the longest string of acerbic speeches from the floor of Congress.

Is she the only 78 year old in America who never has smiled?

There are two constants every day of her noisy life:

• She is irrationally mad at someone,
• A perceived slight was visited upon her minutes ago, and she is positive that it is because she is black and a woman, a professional victim.

After decades of following her, I never have heard her concede that her latest foe merely was contesting her on intellectual grounds. Instead, she argues vociferously that she and her rival are in a death grip because her opponent noticed that she is black and a woman.

USA Today, one of the pillars of the fake-news media, took up her latest cause yesterday under the headline: “Black Woman Demand Their Due Respect.”

One night this week Bill O’Reilly joked about her James Brown-style wig/hairdo during another fiery oration in Congress.

During the predictable subsequent nuclear fallout, insecure liberal women across the country rushed to her defense. Then they asked what the issue was.

Mr. O’Reilly later apologized.

When the lady pops off, does anyone pay attention.

Living a life of moderation and measured responses, she ripped off a whopper in January.

After President Trump was elected and before he was inaugurated on Jan.  20, she prudently called for his impeachment.

Thank you, moderation.
