§ The map · Pennsylvania
Pennsylvania ratified the Constitution in 1787, by a convention vote of 46-23, the 2nd state to do so.
Ratified in five days. A third of the convention voted no.
Asked how many people in the other party support political violence, Pennsylvania residents put the figure at 55.9%. Asked the same people whether they themselves support it, the answer comes back at 15.6%. The distance between what is believed and what is true is 40.3 points, across 6,072 respondents in Pennsylvania.
Divided Houses is about what a country does after it stops checking whether the thing it believes about the other side is true.
