To vote for Zach in August if you aren't already a registered Democrat or Unaffiliated voter, you must either affiliate as a Democrat by noon on June 3rd OR register as an unaffiliated voter by noon on June 3rd and declare affiliation as a Democrat on the day you vote.

You can check your voter registration and change your party affiliation by going Kansas Online Voter Registration. 

You can also visit ksvotes.org to make this change.

Note: Previously affiliated voters cannot change their affiliation on the day of the election; this must be done prior. You can easily change your affiliation back after you’ve cast your vote for Zach in the primary.
