Yep. A lot of the other candidates haven’t released their detailed plans yet either. It’s traditionally done in this post-Labor Day phase of the race, so Trump, like the others, is right on schedule—but somehow Trump detractors try to make it look like he’s particularly deficient and delinquent.
(Heck, Biden, Jerry Brown, Mitt Romney, etc., are still making noises about getting in the race—and so they haven’t released any official positions yet.)
It's called "looking for a problem to have."
