If the Republican plan to overhaul health care fails, the president of the United States will have to face a serious quandary.

Which issue will become his top priority item?

Donald Trump said his first order of business was to repeal and replace the Affordable Care Act. His effort is now gasping for air. A vote on Friday stands as a now-or-never effort. If it fails, which it appears will occur, he will move on to other matters.

What’s next? Let’s see. Building the wall along our southern border? Renegotiating the North American Free Trade Agreement? Bringing back all those jobs that have moved offshore to China?

He won’t deal with Russian aggression in Ukraine, Syria or its meddling with the U.S. presidential election. That’s pretty much a given.

Trump, though, will have to pivot rapidly from health care overhaul.

Heaven knows he’s got a full plate of top-drawer issues to handle.

He did refer to the U.S. economy as a “disaster.” Oh, wait! Then he got that great jobs report for February in which non-farm payrolls grew by 235,000 individuals; joblessness fell to 4.7 percent.

And, no-o-o-o, the numbers weren’t cooked.

I am watching all this flailing right along with the rest of the country. The president cannot get his footing. He has been unable to fill many top administrative posts. He must appoint more than 140 federal judges, which is a consequence of Republicans blocking Barack Obama’s efforts to fill those vacancies when he was president.

And then …

We’ve got all those questions about Russian connections with the Trump campaign, the president’s bogus assertion of wiretapping and whether Donald Trump has any idea of just how he intends to actually govern.

Think of it: We’re only at Day 63. My head is spinning.
