Thirty-three U.S. states and territories report the party affiliations of registered voters as indicated on their voter registration forms. In states with closed primaries, affiliation with a political party can be a condition of participation in that party’s primaries. The remaining states either do not request partisan affiliations on their registration forms or they do not report the totals publicly.
The map below shows the 33 states and territories that display voter registration figures publicly. Note that the U.S. Virgin Islands does not appear on this map.
