You make all your votes at the same time. Players who vote after you will know all of your votes when making their own.

Ballot Broker’s ability is cumulative. If you control two of them, you can vote up to three times.

The ability only affects spells and abilities that use the word “vote.” Other cards that involve choices, such as Archangel of Strife, are unaffected.

You must make your initial vote, even if you decline to vote an additional time.
