Speaker of the U.S. House of Representatives Paul Ryan is partially correct when he says the nation “is becoming divisive.”

I believe we’re already there, Mr. Speaker.

It’s not a condition that has just developed overnight, or certainly during the current election cycle.

It seems to my reckoning to have its roots in the 2000 election season, when a candidate for president was elected by the narrowest margin imaginable — and under circumstances that to this day hasn’t been accepted by many millions of Americans.

George W. Bush won the presidency after the Supreme Court stopped the recounting of ballots in Florida. The Texas governor had 537 more votes than Al Gore in that state. He won that state’s electoral votes, giving him the election — even though Gore had amassed more popular votes nationally than Bush.

For the record, I’ve never doubted the legitimacy of Bush’s election as president. The constitutional system worked.

But …

The spillover through the next several elections has seen a palpable division among Americans.

The current campaign has delivered an intense ratcheting up of the division that’s been there for some time now.

I’m not a fan of the speaker, but I do applaud him for speaking to our national idealism. He clearly was taking dead aim at the tone being delivered on the campaign trail by Donald J. Trump, who he didn’t mention by name. Everyone in the congressional conference room who heard Ryan knew of whom he was speaking.

As Politico described Ryan’s remarks: “He decried identity politics, criticizing those who pit groups of Americans against each other. He said the nation’s political system doesn’t need to be this bad. He accused both parties of staying comfortably in their corners, only talking to those who agree with them.”

Ain’t that the truth?

There once was a time when members of Congress — from both parties — talked openly with each other about how to legislate for the good of their states or the country. The Texas congressional delegation was known to have bipartisan breakfasts weekly, with House members breaking bread with each other and talking about issues that needed attention.

It doesn’t happen these days.

Instead, we’re seeing and hearing candidates and their rhetoric demonizing “the other side.” The No. 1 instigator of this campaign-trail anger is the GOP’s leading presidential candidate — Trump.

Ryan’s message will not resonate with the segment of the population that has bought into the Us vs. Them mantra that Trump and others are promoting. Ryan is now seen as a member of the hated “establishment.”

Ryan said: “What really bothers me the most about politics these days is this notion of identity politics. That we’re going to win election by dividing people. That we’re going to win by talking to people in ways that divide them and separate them from other people. Rather than inspiring people on our common humanity, on our common ideals, on our common culture, on things that should unify us.”

Is his message too sunny, too optimistic, too idealistic?

For the sake of our political future, I hope not.
