It fascinates me how people are so willing to just cut these working class guys off because they support Trump. They're hurting pretty bad these days, what with automation and rampant outsourcing, but because a lot of them don't have good educations (because they don't have access to decent resources) the left are content to let them rot.
The reason they support Trump is because he promised them their old jobs back and that he'd fix their problems. Whether or not he's done that is yet to be determined, but the fact is the left ignored them in favor of identity politics, and we all saw how well that turned out. But rather than help the working class, the left would rather turn their noses up at them for supporting the opposing side.
And it's people like Bob who don't realize they're the side who's alienating the general public by saying things like that.
