Donald Trump is going to unveil his immigration reform package.

It shouldn’t take long for him to tell us his plans if he is elected president of the United States. As I understand it, the plan will look something like this:

Build a wall and then deport all the undocumented immigrants immediately.

If there is anything that resembles a centerpiece of the Trump campaign, immigration appears to fit that description. He made quite a splash regarding immigrants when he announced his candidacy in June. Mexico, he said, is “sending” criminals to the United States. Murderers, rapists and drug dealers are being sent here. “Some, I assume, are good people,” he added as an afterthought.

Trump said he plan to rescind President Obama’s executive order granting temporary amnesty for as many as 5 million illegal immigrants, which of course has drawn high praise from Republican audiences. “We will work with them. They have to go,” Trump said. “We either have a country or we don’t have a country.”

I have just a couple of thoughts regarding the Trump Immigration Reform Plan.

How much will it cost to build an impenetrable wall across our southern border? Do we have the money?

How does he intend to search for and locate every one of the undocumented immigrants who are living here? And what does he intend to do with the children of those undocumented individuals who were born in the United States and have earned U.S. citizenship just by being born in this country?

And what might Trump propose to do with those individuals who entered the country illegally but who have become successful businessmen and women?

All of this is going to require the detail, nuance and thoughtfulness that’s been missing in Trump’s campaign to date.

Then again, why should he provide it now? Those polls that show the real estate mogul leading the GOP field suggest many of the party’s primary voters don’t care about those things.
