We’re less than a month away from the official beginning of the 2020 Primaries and Caucuses! 50 states, 5 territories, the District of Colombia, and voters living abroad will be participating in caucuses and elections between early February and early June as part of the lead up to November in order to determine which candidate will represent the Republican and Democratic parties.
Democratic contests will be held in all 56 locations (as well as abroad), but Republican contests have been cancelled in Alaska, Arizona, Hawaii, Kansas, Nevada, South Carolina, and Virginia.
Registration deadlines, voting/caucus procedures and dates vary from place to place, so we have put together this table to help you find out more information about how, where, and when you can participate. Follow the links for location-specific details and note the information regarding party-switching deadlines and caucus types at the bottom of the table.
And as always, please be mindful of following the rules of /r/politics when participating in discussion threads.
