Donald J. Trump has made quite a show of trumpeting his “great” poll numbers while rolling to the Republican Party presidential nomination.

Indeed, the real estate mogul’s main selling point for months has been those polls. They’re up, therefore they’re legit.

But wait! The polls lately are trending in another direction.

Hillary Rodham Clinton has retaken the lead over Trump in their campaign for the presidency. The Democratic nominee has gotten an expected “bounce” from her highly successful convention.

Trump’s view of polls now?

They’re “rigged,” he says. He doesn’t believe them. CNN and some other media organizations are cooking the numbers to show Clinton with a phony lead, Trump says.

OK, then.

Let’s just shield Trump from all the bad news that inevitably will come his way, just as it flows toward Clinton when things don’t always go in the direction she prefers.

As for his fixation only with positive poll numbers and his outright rejection of those surveys that show him down against his opponent, I have just a simple piece of advice.

Suck it up, soldier! The only “poll” that counts is the one on Election Day. Then again, my gut tells me the GOP nominee is going to get another dose of very bad news when that day arrives.
