Here comes the defense of Donald J. Trump’s hideous declaration on national TV this week that women should be “punished” if they obtain an illegal abortion.

He was speaking “off the cuff” during a town hall meeting that was televised by MSNBC. That’s what the Republican presidential campaign frontrunner’s spokeswoman told Fox News.

Many of us heard Trump make the statement under intense questioning from Chris Matthews. We also heard about his immediate reversal.

Trump needs to understand something if he has a prayer of avoiding a complete implosion of his presidential candidacy.

It is that there are a number of issues that require deep thought and nuance when the candidate is pressed to discuss them.

They include, oh: nuclear proliferation, climate change, immigration reform, health care reform and, yes, abortion.

I’m sure others are out there, too.

Trump’s flack, Katrina Pierson, told the Fox News Channel, “Well I say when you are a political candidate for eight months, you are speaking off the cuff. That’s one of his appeals, that he’s not a scripted politician.“

What is so wrong with thoughtfulness?

Scripted pols learn that their words matter. Unscripted pols need to get that, too. When the subject turns to abortion — an issue that gets zealots on both sides of the divide worked up into a frothing frenzy — then those words matter a great deal.

Trump hasn’t gotten it. He likely never will get it. He’ll keep on speaking “off the cuff” on issues that require some study, soul-searching and a comprehensive understanding.

Pierson is right about Trump’s “appeal” to those who keep laughing off this stuff.

It’s not funny.
