"Party ID Trends"
Here’s a graph I made off some Pew data that Paul Rosenberg pulled. On the one hand, you see that the GOP collapse over the past couple of years has been truly dramatic. On the other hand, you see that these party ID numbers are pretty volatile and can change a lot in response to events, so it’s not totally clear what this signifies for the long run. The short-term opportunity for Democrats, however, is hard to miss.
