If you’re registered as No Party Preference…
… and you want to vote in the Democratic Presidential primary.
If you want to vote in the Democratic Primary for the Presidential election, but not the DCCC race, you’ll need to request a “crossover” ballot for the Democratic Presidential Primary using SF’s Voter Portal or your county’s equivalent.
Do this ASAP, especially if you’re a vote-by-mail voter—ballots go out shortly before February 3rd, and you want to make sure they’ll send you the right one!
In the SF Voter Portal, the option to request a crossover ballot is in the “Apply to Vote-by-Mail” tab. Yes, even if you’re already a vote-by-mail voter. Note that this is a permanent selection for this election—once you’ve requested a crossover ballot for a particular party’s primary, you can’t change it online.
You can also request a Democratic crossover ballot by other means, documented on the SF Department of Elections’s website. If you’re not in SF, your county’s website should have instructions on how to do it in your county.
… and you want to vote in my county’s DCCC race.
If you want to vote in the DCCC race, you must re-register as Democratic, using the same process that folks who aren’t registered use.
Re-registering as Democratic will also ensure you can vote in the Democratic Presidential primary. You won’t need to request a crossover ballot if you do this.
… and you don’t care about the Presidential primary or the DCCC race.
You can always vote in “open” primaries such as your House of Representatives district primary, regardless of your own party affiliation, so if that’s all you care about, you don’t have to make any changes.
I’m registered as a Democratic voter.
You can vote in the DCCC race and the Democratic Presidential primary. You don’t need to change anything.
But, if you’re not already a vote-by-mail voter, you can opt into that using SF’s Voter Portal (if you’re in SF), or by other means provided by your county.
I’m registered with some other party.
If you want to vote in the Democratic Party’s primary and/or your county’s DCCC race, you’ll have to re-register as Democratic (or as No Party Preference and request a crossover ballot as described above, but that’s the long way around).
