So now it’s U.S. Sen. Ted Cruz weighing in on Donald J. Trump’s re-election chances. Has the Cruz Missile discovered something the rest of us don’t know? No. But he’s blathering anyway.

Cruz appeared on PBS’s “Firing Line” and told the host, Margaret Hoover, that the president “absolutely” could lose his re-election bid. Well, duh! Do ya think?

Cruz also said he doesn’t believe Democrats will nominate a centrist, such as, say, former Vice President Joe Biden. They will nominate a lefty in the mold of Sen. Elizabeth Warren, Sen. Kamala Harris or Sen. Bernie Sanders. He said the far left of the party is calling the shots and will turn away from a candidate deemed to be too, oh, “moderate.”

He also believes the left is so enraged at Trump’s presidency that they’ll turn out in staggering numbers.

None of this is really a big-time flash. Cruz well might be correct that Trump’s chances are a big dicey at the moment. However, we’re talking about the here and now. The future could reveal something quite different.

It pains me terribly to acknowledge this, but Donald Trump was considered a joke when he announced his candidacy prior to the 2016 Republican primary season. Then he knocked off all those challengers one by one; Sen. Cruz was one of them.

Then he got nominated and ran against Hillary Rodham Clinton, a candidate perceived to be infinitely more qualified. Then all hell broke loose. Hillary lost to The Donald.

Ted Cruz’s prognostication today, therefore, means next to nothing.

Still, it is a bit scintillating to ponder that a former Trump antagonist who’s turned into one of the president’s most ardent allies would consider the POTUS to be in some jeopardy.

If only …
