So Trump built a booming economy. But when you ask how, you get zero details.
Just like when folks on the Right would whine that Obama was ruining the country, and I'd ask how and get absolutely nothing in return. Out of 10 Obama Ruination folks I asked, only one gave an answer, and that was that O's executive orders were unconstitutional. I pointed out that executive orders were fairly standard, and asked which of them had harmed the country, but then they weren't playing details and facts with me. They had caught on to my game of rational discourse and factual debate.
So Trump's we built a booming economy once and can do it a second time appears to be just an empty slogan with no substance. Imagine that. Or maybe Trump has another secret plan to bring back coal and manufacturing jobs, which was a key of his initial plan to build a booming economy.
