Political money has excellent manners. Ask it to leave the campaign account and it will politely hire its own loudspeaker outside.

CalMatters reports that both Democrats running for California insurance commissioner, Ben Allen and Jane Kim, pledged to reject insurance-industry contributions. An outside committee supporting Allen nevertheless received insurance-related donations, including $48,000 from a health insurance PAC. Allen said he neither sought nor welcomed the spending.

That distinction is real. Independent committees operate separately and cannot legally coordinate with campaigns. Candidates cannot return money those committees received. The reporting also notes Allen’s consumer-protection record. This is no basis for declaring a secret deal.

It is, however, an excellent reason to examine what a pledge can accomplish when the money comes equipped with its own publicity department.

An ordinary voter hearing that a candidate refuses industry money might reasonably imagine less industry influence surrounding the campaign. The campaign-finance system hears a narrower instruction: please direct the funds to the other business entrance. The check has been declined; the amplification remains available in several convenient sizes.

The industry does not need to put a candidate on its payroll to have political preferences. Nor does a candidate need to request the assistance for voters to care who is paying to provide it. Those are different questions, and a reassuring answer to the first should not be allowed to swallow the second.

Which makes the consumer’s job unnecessarily elaborate. First read the candidate’s pledge. Then examine the independent spending. Then decide what weight to give the candidate’s actual record. Somewhere in there, remember that the office exists to regulate insurance, a task for which voters might prefer a clearer picture than a diagram of who is technically standing where.

Allen deserves to be judged on what he has done and would do. Every donor deserves to be visible while trying to help determine who gets the job.

A clean campaign account is useful information. It should not become a blindfold with exceptionally tidy bookkeeping.
