For the record, here’s the Democratic turnout in New York in 2008 and 2016:
Total Turnout
18-29 Turnout
2008
1.82 million
273 thousand
2016
1.81 million
322 thousand
The turnout rate among all residents aged 18-29 was up from 9.8 percent to 11.5 percent. That’s a nice increase, but as I recall, Obama didn’t spend a whole lot of time in New York in 2008. When you take that into account, it’s hard to see much evidence here of a massive surge in youth interest caused by the Bernie Sanders campaign.
