Does anybody have precinct-level election results for the USA? A set for recent elections would be great for public access redistricting apps that will become relevant this year.

For those interested in transit data, check out the GTFS Data Exchange, a directory of many agencies' scheduling and map data, following the Google Transit Feed Specification.

Kinda surprised no one has mentioned Factual. I'm using some of their diabetes data for my side-startup. http://www.factual.com/

Their write that most the data is available for download. I can't find it anywhere though, only the various APIs. Have they remove the possibility of downloading the data?

It's not exactly neighborhoods, but the US Census TIGER database has block and blockgroup boundaries with associated demographic data. You could probably synthesize that into "neighborhood" definitions. http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.ht...
