The cable news networks are all abuzz with the idea that Donald Trump will steal middle income (union) workers in the Rust Belt away from the Democrats (and Hillary Clinton). But as the top chart shows, that is not true -- at least for now. In the states of Michigan, Ohio, Pennsylvania, and Wisconsin, those middle income voters still prefer Clinton over Trump by a 7 point margin.
The chart was made using results from a Bloomberg Politics / Purple Insights Poll -- done between May 18th and 24th of a sample of 803 middle income voters ($30k - $75k), with a margin of error of 3.5 points.
As the bottom chart shows, a plurality of those voters also expect Hillary Clinton to win the presidency.
