Primary Rules

How District of Columbia's Primary Works

District of Columbia uses different primary rules for state/congressional and presidential elections

State / Congressional

Semi-Closed Primary
Registered party members vote in their own party's primary. Unaffiliated voters may choose a party primary to participate in, but voters registered with a different party cannot cross over.
How It Works
If you're registered Democrat, you vote in the Democratic primary. If you're registered Republican, you vote in the Republican primary. If you're unaffiliated, you can pick either; you may need to formally affiliate at the polls.
IVP's Position
An improvement over closed primaries, but still ties the system to party labels. Voters shouldn't have to join a private organization to participate in publicly funded elections.

Presidential

Closed Primary
Only voters registered with a political party can vote in that party's primary election. Independent and unaffiliated voters are excluded.
How It Works
Voters must register with a party, often weeks or months before the election, to participate. If you're registered as independent or unaffiliated, you cannot vote in either major party's primary.
IVP's Position
Closed primaries lock millions of independent voters out of the elections that matter most. In many districts, the primary is the only competitive election.
