It doesn't matter. Trump claimed he'd build the greatest economy again. He didn't provide any details on what he plans to do that will actually improve people's lives. He just let people jump to their own happy conclusions.
He did provide high level detail. He said he'd use tariffs to exclude foreign made stuff, which will necessitate "made in America" and bring manufacturing back. He said he'd balance the budget, which (theoretically) has long-term effects. He said he'd deport illegals, which should reduce demand for housing and hence prices.
You can disagree with any of those things, but I don't think it's right to say he didn't offer anything specific.
I mean; he offered 'specifics' - they simply didn't make any sense on cursory examination. How to fight inflation? Tariffs! How to make already expensive goods cheaper? Tarriffs!
Hell, re: deporting illegals, he didn't even bother to do that his first term, Obama did it at a dramatically higher rate.
It's all a "I'll fix everything by doing nothing" smokescreen.
No, but he had a very simple and catchy message that even people with the lowest IQ can understand and remember: "Fuck illegal immigrants, fuck China, America first, USA no. 1".
Election messages need to appeal to the lowest common denominator of education and intellect. If you start boring people with facts and high brow speeches that only the well educated can understand, you lost from the start.
Republicans understand that the less educated a voter is, the more likely they are to vote R. It's not a coincidence that they are trying to gut the education system.
