According to the PA website, voter turnout was 67.63% in 2012 and 68.65% in 2008.
PA voter turnout was 84.8% in 1968 (The Deer Hunter was set in 1967). Humphrey carried the state. Turnout was 78.2% in 1972 (Nixon, landslide).
PA voter turnout was 79.3% in 1980 (went for Reagan) and 78.2% in 1984 (went for Reagan).
Philly, for all its shenanigans, doesn't have as high a voter turnout as the suburbs and rural areas. (58.8% in 2012.)
I *think* that there are a lot of PA blue collar voters who believed that they would get screwed no matter who they vote for (1996-2012 is when the turnout fell), and this IMO is where the Republicans should focus their efforts.
Nice analysis. Forward that to Manafort.
