I watched Donald J. Trump make his big announcement this morning.

He stood before a row of Old Glories to introduce Indiana Gov. Mike Pence as his Republican Party vice-presidential running mate.

I sat there, in front of my TV. I waited. And waited. And waited some more. I waited for Trump to stop talking about himself — often in the third person — and waited for him to say something good about the guy with whom he’ll run for the White House.

The presumptive GOP nominee prattled on and on for nearly 30 minutes, boasting about his primary victory over a huge field of candidates.

He railed against Democratic nominee Hillary Rodham Clinton. He talked about how free trade is bad for America, about how NAFTA has siphoned jobs from the United States to Mexico.

Then he got around to introducing Pence, who then delivered a fairly straightforward pasting of Clinton and the Democrats. He also said a few nice words about Trump, who he called a “good man.”

Pence, by the way, voted in favor of NAFTA and CAFTA while he served in the House of Representatives. The two candidates are going to have to come to an understanding on trade policy, yes?

Mike Pence’s big day turned out to be, oh, Donald Trump’s big day.

Is that a surprise? Heavens no!

The commentators who opined about the Pence roll-out noted something quite interesting: Sen. John McCain of Arizona spoke for 7 minutes while introducing Alaska Gov. Sarah Palin in 2008; former Massachusetts Gov. Mitt Romney spoke for about 10 minutes before unveiling Rep. Paul Ryan of Wisconsin in 2012.

McCain and Romney spent their entire time talking about their running mates. That moment was about them, not the men at the top of their tickets.

Trump didn’t do it that way.

Naturally!
