More interesting signals:
* The constitutional amendment in Florida for abortion access (Amendment 4). If that comes in higher than around 60% then that's a _very_ strong signal for some of the other states given the importance of this issue for a lot of voters.
* A few commentators have pointed out that Osceola has a very dense Puerto Rican population. This could be a useful signal on Pennsylvania (which we won't have results from for a good bit, in all likelihood)
