I met someone the other day, a building contractor, who told me he was a strong supporter of Trump. He said that when he went into a store to buy a chisel, of the 8 available, only one was made in the USA. He also called Walmart "China-mart", in a derogatory way. 

My take is this: Pretty much on almost any issue you can name, there are a huge number of people who don't understand how the ...(fill in the blank - economy, military, government, foreign relations, et al) actually work. They are, ironically, much like Trump himself in this respect. But like him, they *think* they know how these institutions and protocols work. So, for instance, this guy sees chisels mostly from China, and buys the Trump narrative that the biggest economic problems are that places like China are stealing USA jobs. It never occurs to them that the reason all these jobs have gone overseas are not unfair trade practices (which of course they pick up from Trump), but that US workers can't, and never will, be able to match developing countries on wages and costs. So yes, they're fully behind a trade war, because Trump has told them this is what's been eroding job growth at time. Even as we have record employment. It'd be interesting to see how the job growth in the US is segmented - i.e., white collar, blue collar, industrial vs. service, etc.
