Age demographics skew old even for PA, one of the oldest states in the country. In 2012, 17% of the PA electorate was 65 or older. PPP has 23% of the electorate as senior citizens.
PPP also projects that 80% of the PA electorate will be white when only 78% of PA voters were white in 2012 and most of the voter population loss was older white voters while a disproportionate number of new voters in the state are non-white (especially Latino, even there)
Here we go again. Stop unskewing the polls!
We have two white candidates who're extremely (especially Trump) unpopular among youngs. I wouldn't be shocked, if we'll get more seniors and more whites than usual.
