Don't forget these Pennsylvanians are the ones Barack was referring to when he made this famous statement:
You go into some of these small towns in Pennsylvania, and like a lot of small towns in the Midwest, the jobs have been gone now for 25 years and nothing's replaced them. . . . So it's not surprising then that they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations. (emphasis added).
So all those good, hardworking people Pennsylvania must be asking themselves: Why on earth would I support a party that thinks I'm nothing more than a racist redneck (too ignorant to understand my own economic interests), who's "cling[ing]" to guns and religion because that's all I've got?
