The summary chart is too big to cut-and-paste, so I will just link to it.

Basically, it is another Clinton-Trump poll and it shows Clinton leading Trump by 9 points.  But then it compares this presidential race to the polling in June of 2012 and June of 2008 to see where the demographics of the electorate have changed.

Here are a few takeaways that jump out at me:

• Young women have, and continue to be strong pro Democrat, but this has leaped a lot this time around (D+14 in 2008, D+15 in 2012, D+24 in 2016)
• Huge shift in higher education to Democrats. For those with postgrad degrees, it’s D+3 in 2008, D+10 in 2012, D+27 in 2016.  College grad: D+1 in 2008, D+3 in 2012, and D+16 in 2016.
• Also a huge shift in upper income from Republicans to the Democrats.  For those making >$100,000, it’s R+10 in 2008, R+3 in 2012, and D+8 in 2016.
• Sadly, there is no comparative data for 2008 and 2012, but Hispanics are D+42 this time around.
