From a purely political standpoint, Trump's biggest problem is that he's tailored his campaign to appeal to a shrinking base of Americans who actually aspire to work in factories. I know a few people whose parents worked in factories. They are all immigrants, and none of them will be voting for Donald Trump.
The car factories in Alabama and other places in the South are non union and people have good jobs. When you get the unions out of the car business its profitable here.
I think Trump knows all this. He says a lot of stuff for effect. He wants to renegotiate every trade agreement and also lower the corporate tax rate to get business back in the states. So do I. I’m sure Trump knows that Mexico rips us off because NAFTA allows it to.
He needs to refine his message.
