It's more than obvious that the marriage of Donald Trump and leading Republicans isn't working. And it's not just Paul Ryan— Reince Priebus, Mitch McConnell and other top GOP officials are obviously uncomfortable with Trump.

The fact is, Barack Obama made a perceptive and hard-to-refute point when he said of Republican leaders on Tuesday, "The question I think that they have to ask themselves is, if you are repeatedly having to say in very strong terms that what [Trump] said is unacceptable, why are you still endorsing him?"

Nevertheless, Ryan, Priebus, McConnell and others — party men all — would have a very difficult time disassociating themselves from the man their voters chose to be the Republican presidential nominee. So perhaps the nominee should disassociate himself from them.

One way out of the current Trump-Ryan mess would be for Trump to release Ryan from his endorsement of Trump. The speaker clearly doesn't want to have anything to do with Trump, yet was forced by the voters, by party loyalty and by custom to endorse. Of course, Trump has no love for Ryan, either. It's hard to imagine two more different men, on opposite sides of a very deep party divide.

So Trump could say something like this:

I have great respect for Speaker Ryan, but it's clear that our partnership isn't working.
The speaker has strong beliefs. I know, for example, that he does not agree with my plan to build a wall, secure our borders and protect Americans from criminal illegal immigrants.
I know that he does not agree with my plan to keep radical Islamic terrorists out of our country.
I know that he does not agree with my plan to ensure trade agreements are fair to American workers first and foremost.
And I also know that I don't agree with his plan to cut your Medicare and Social Security.
So while I wish Speaker Ryan the best, and I look forward to working with him when I am president, I will stay out of his race for re-election and I will release him from his endorsement of me.

In one statement, Trump could lance a pretty awful political boil, and at the same time make a straightforward appeal to independent voters. He could also re-frame the current dispute around actual policy issues, instead of compassion for Gold Star parents or other questions of temperament.

It's just a fact that in many policy areas, Trump is not an orthodox Republican, and is in fact the opposite of Ryan. A Trump-Ryan divorce could make that clear, perhaps to each man's benefit.
