I’ve been waiting for this declaration.

Today, it finally came from U.S. House Speaker Paul Ryan, who declared that he will not accept the Republican Party’s presidential nomination if it’s offered to him.

There. It’s a done deal.

Ryan’s declaration spells out a gloomy prospect for the Republican Party. It’s going to nominate — more than likely — one of two men who hold tremendous negative ratings among rank-and-file voters.

Donald J. Trump will go to the GOP convention with more delegates than anyone else. U.S. Sen. Ted Cruz of Texas will show up with the second-most delegate stash.

Neither of these fellows is going to defeat probable Democratic nominee Hillary Rodham Clinton, although surely their partisans will argue differently.

Ryan might have been able to rescue his party from what could turn out to be an electoral landslide loss. He’d bobbed, weaved, dodged and danced all over the question about whether he’d be open to a draft at the convention in Cleveland, Ohio.

“Count me out,” he said today. The convention should nominate someone who “actually ran for the job,” he said.

Don’t misread my intention here.

I don’t think Paul Ryan should become the next president. I voted against the ticket on which he ran in 2012 as the VP nominee with GOP presidential nominee Mitt Romney.

It would have been a fascinating development in the extreme, though, to see whether the convention could turn to him as a sort of political savior.

It won’t happen.

Now the party is left with a sour choice.
