After the initial 7 days, the voting period starts and lasts for 14 days. Once you submit your vote, you cannot change it. The voting power is equal to a validator’s total ONE token staked, and can vary in terms of voting power depending on delegation or undelegation. We have made this choice to passively include delegators in the governance process. If a delegator does not agree with the vote of the validator he/she delegated to, he/she can simply redelegate to another validator, to support it’s vote.
