Don’t sit down, Gov. Eric Greitens. I’m going to talk about you for a moment.

This fellow is a Republican governor from Missouri. He’s been in office for only about a year. He also is making quite a name for himself.

He ran for office as a “family values” candidate. He once proclaimed his love for his wife and children and the happiness he feels at being a married man and father.

The former Navy SEAL — who was a Democrat until he switched parties in 2015 — was even discussed as a possible presidential candidate in 2020 or 2024.

Then came this: He fooled around with a woman other than his wife before he was elected governor. What’s even more troubling is that he allegedly threatened her if she blabbed about it.

The woman, who was married at the time, is now divorced from her husband. Greitens remains married to his wife. He admits to the affair, but denies threatening the woman with whom he took the tumble.

Family values …

Wow. What are we to make of political candidates who make such a big show of their marriage? How are we supposed to react when they get caught in the big lie? I take this kind of thing quite badly. It doesn’t go down well. Why? Because of the show politicians such as Greitens make when they actually boast about their marital fidelity on the campaign stump — as if someone keeping a vow he makes before God is worth a boast.

This clown reminds me of so many politicians who’ve proclaimed their love for the spouse only to be revealed to be philanderers.

Does the name John Edwards ring a bell? Edwards was the 2004 Democratic vice-presidential nominee who campaigned across the land declaring his devotion to his late wife, Elizabeth — while he was messing around with a woman who later gave birth to a baby, courtesy of that relationship with Edwards.

This kind of revelation sickens me in the extreme. Gov. Greitens makes me sick, too, given that he made such a phony show of his marital devotion.

Politicians who lie about their faithfulness then deserve all the scorn they receive.

Now … you may sit down, Gov. Greitens. And may you disappear from the national political scene.
