Our paper introducing the "American Local Government Elections Database" is online at Scientific Data. The data includes 78,000 candidates in 57,000 electoral contests in races for seven distinct local political offices in most medium and large cities and counties over the last three decades.

In our PNAS we don't necessarily find a negative relationship between affpol and antidemocratic norm support, but certainly a non-linear one (appendix fig. below).

Personally, I think FT measures have some pretty major empirical oddities we're still evaluating
