Trump isn’t talking about the morality of the issue, but about the political reality of it.
The political reality is that it’s a violation of security and privacy. That also makes it wrong.
True. Trump is shifting past primary campaign mode and getting ready to dismember Hillary.
Lots of Sanders voters are going to feel ripped off. He wants them to vote Trump or stay home. Look for him to sound “reasonable” on hot button issues without really committing to any course of action.
On Hannity, he later said it was an issue for the states. That’s a pretty conservative view.
