They voted for 0bama, twice. I never thought I’d say it, but PA is in play. Trump has to hit the jobs front, soon and hard. Pennsylvania can power the US with its massive gas and coal reserves. The pipelines just have to get put in place and the rail lines restored.
In order for Trump to have any chance in PA he will have to do reasonably well in the suburbs surrounding both Philadelphia and Pittsburgh. Even if he carried the rest of the Commonwealth there are just too many people in those two metro areas that are a major influence on statewide elections. You can all but forget about voters within those two city limits. It’s the suburbs that need to be concentrated on.
