Primaries vs. General Elections
Primaries narrow the field of candidates. The general election then decides who wins the office. Who can vote in a primary depends on your state.
The basics
- A primary is an election that decides which candidates move on to the general election. In a party primary, voters pick who that party will nominate.
- Closed primary: only voters registered with a party can vote in its primary. Open primary: any voter can choose one party's ballot privately, without joining that party.
- Some states are in between. For example, some let unaffiliated voters pick a party's primary while party members stay in their own party's primary.
- In a top-two primary, all candidates share one ballot no matter their party, and the top two move on, even if both are from the same party. As of October 2026, Alaska sends the top four.
- Caucuses are local meetings run by a party, used in some states to help choose presidential nominees. Rules on all of this vary by state, so check with your election office.
Why it matters to you
The primary decides whose names you will see on the general election ballot. If you skip it, other voters narrow your choices for you.
Myth vs. fact
MythAnyone can vote in any party's primary.
FactIt depends on the state. Some primaries are open to all voters, while others are only for registered party members.
MythThe general election always has one candidate from each major party.
FactNot always. In a top-two system, the two finalists can be from the same party.
Where people disagree
Should party primaries be open to all voters, or limited to party members?
Supporters of open primaries say
- Voters get more flexibility to pick the race or candidates they care about most.
- Voters can keep their party choice private instead of having to register with a party.
Supporters of closed primaries say
- It discourages voters from another party crossing over to sway who gets nominated.
- It lets a party's own members choose their nominee, which they say supports stronger parties.
We present the main arguments fairly. We don't take sides.
What you can do
- Find out what type of primary your state uses and whether you need to register with a party to vote in it.
- If your state has closed primaries, check the deadline to change your party registration before the primary.
- Put both the primary and the general election dates in your voting plan.
