Bearing in mind that the subject may - strike that, almost certainly will - come up elsewhere, we found this interesting:
Oregon's secretary of state, Bill Bradbury (a Democrat) and California's, Bruce McPherson (Republican), have released a "neutrality pledge." They didn't seem to overtly suggest their counterparts elsewhere (and both Washington and Idaho have secretaries of state, and all these states' SoSes have mostly similar responsibilities) adopt it too, but the subtext seemed to be there. The idea for the pledge evidently grew out of meetings of the National Association of Secretaries of State.
Here are its five points:
I will not serve in any ongoing capacity on a campaign supporting any candidates.
I will remain neutral, will not raise or contribute funds, and will not serve in any ongoing official capacity on a campaign supporting any referendums, measures, propositions, recalls or initiatives, unless they relate directly to the official duties and responsiblities of the Secretary of State.
I will not take any action in my official capacity as Secretary of State for the purpose of directly benefitting or disadvantaging any candidates, referendums, measures, propositions, or initiatives.
I will pledge to follow the current campaign finance and disclosure laws that apply to candidates for statewide office.
If I am a candidate for any office, this pledge will not restrict me from any otherwise legal campaign activity on my own behalf.
May prove interesting if the subject arises . . .
