This is what Bennett said to Josh Marshall -
"This afternoon I spoke to Dick Bennett, president of ARG. And here's what he told me.
On Wednesday evening, ARG interviewers (i.e., the folks who call you on the phone) started noticing that a number of older independent voters were screening themselves out of the survey because they'd been called by another campaign and told that they wouldn't be eligible to vote because they'd missed the deadline to declare as Democrats.
But that's not how New Hampshire law works. Independents (called undeclared voters in the state) can vote in either primary. And they don't have to decide till they're at the polling station.
ARG's interviewers kept hearing the same thing on Thursday night and Bennett told TPM he found out about it when one of his supervisors asked him whether the voting law in the state had been changed.
Bennett said his interviewers had not compiled a list or numbers of how many people they called who had mentioned this. But his interviewers apparently spoke to quite a few respondents each evening who had gotten these calls.
Based on that information, Bennett decided to mention it in his daily poll analysis."

I still think Bennett should have forwarded the information to reporters and let them check it out. But Bennett wasn't acting on weak information, as asserted this morning.
Nothing to Dean with Dean campaign in my view.
