FIFTY-NINE YEARS AGO, William Proxmire, of the now-Rust Belt state of Wisconsin, took the floor of the US Senate in support of a bill that would lower tariffs on imported goods. My then-boss had brought with him a few hundred of the many pro-free-trade letters that our office had received in support of the bill.
Every single letter was written by a member of the United Auto Workers. At the time, it was not difficult to find manufacturing workers who supported the liberal agenda of expanded world trade.
But that was then. I'd be willing to bet that many who wrote those letters urging Proxmire to support free trade, and their children, voted for Donald Trump in droves, helping him to carry Wisconsin, the first Republican presidential win there in a generation.
