2020 Presidential Primaries,
Caucuses, and Conventions
Major Events

These pages contain a combination of official, unofficial, and estimated data. The information posted here is subject to change.

The delegate selection processes herein, along with any and all dates and delegate counts associated therewith, are unofficial and based on either (1) information obtained from either Major Party, (2) Presidential Primary dates established by currently-effective State statute, or- where the foregoing information could not be obtained- (3) the state's 2016 delegate selection process and associated dates adjusted to the corresponding dates in 2020.


  • Democratic pledged delegate counts are determined by the jurisdiction's Presidential vote in 2008, 2012, and 2016; along with the jurisdiction's electoral vote allocation based on 2010 census for the number of electors in 2020.
  • Democratic unpledged delegate counts are determined by the number of DNC Members, Democratic Governors, Democratic U.S. House members, and Democratic U.S. Senators serving at the time of the convention. The count for DNC Members, Distinguished Party Leaders is from the 2016 Convention. The tallies of Governors, Democratic U.S. House members, and Democratic U.S. Senators are the current officeholders.
  • Democratic Bonus Delegates and penalties are not included in these delegate tallies.


  • Republican delegate counts are based on the number of Republicans elected to the State Legislatures, Governors chairs, U.S. House seats, and U.S. Senators seats through 31 December 2019. Republican unpledged delegate counts are determined by state (or equivalent) party rules. We have assumed that the policies of 2016 will apply in 2020.
  • The Republican district delegate count is based on the number of U.S. House members each state will elect in 2020.
  • Republican penalties for violating the timing window are not included in these delegate tallies.
