> Last year, YouGov found that only 43 percent of Americans knew Puerto Ricans were U.S. citizens.

> Overall, 64 percent were in favor of aid to the island. ... That 64 percent in favor of aid increased to 68 when respondents were informed that Puerto Ricans are U.S. citizens. Trump backers specifically saw a 10-point jump — from 57 percent to 67 percent — in favoring aid when told that Puerto Ricans are U.S. citizens.

Interestingly, apparently PR is still considered "unincorporated" meaning that the US Constitution doesn't apply in its entirety there.

But you already knew about the statistical peculiarity that was the 2016 Electoral College result, so I'm guessing you're repeating this hoping for some alt-right points on HN? Or just to demonstrate that public policy polling and statistics are somehow a big snake oil discipline that you're too intelligent to fall for?

Anecdotally (i know thats not a good example) most people I speak to always ask if needed a visa to more to one of the 50 states, they ask if you need a passport to visit and they ask if you can drive to PR.
