Note: In addition to official "special" elections, this page may also include candidates running for local office (County, Municipal, etc) who don't fit into other categories.

By default, donations made on this page will be split evenly among the boldfaced funds below, but you can also pick & choose which campaigns to support using the "Customize Amounts" tool.
Note: I include the Partisan Voter Index (PVI) rating for every district where possible according to Dave's Redistricting to give donors a general idea of how tough a district each one is.
