Well, that was fun to watch.

Former half-term Alaska Gov. Sarah Palin endorsed Donald J. Trump for the Republican presidential nomination. She is the queen mother of the TEA Party movement.

The conventional wisdom had been that she’d endorse Ted Cruz for the GOP nomination.

It didn’t happen.

So now  you have to wonder: Has Palin changed her stripes?

TEA Party loyalists — the hard-core folks — call Trump a closet liberal. He’s not the real deal, they say. He used to be friends with (gulp!) Bill and Hillary Clinton, for crying out loud. He’s given money to Democrats.

But then out came Sarah Barracuda today, talking glowingly about Trump.

As for Cruz, he’s now the man left in the cold.

Cruz welcomed Palin to a conservative action conference a year ago, calling her someone who “picks winners.” He called her “principled” and “courageous.”

Is she now all of those things, in Cruz’s mind? I’d bet not.

I never thought the Republican Party primary campaign could get any more fun — or hilarious — than it has been up to this moment.

Silly me. It just did.
