The Hiller Instinct: 7News-Suffolk Poll: DNC Support

Asked if they think the convention is a good idea, 56 percent, a clear majority, say yes with 36 percent, just over a third, saying no. Our pollster says it's all about zip code.

"The further away you are, the more supportive these respondents were about the convention. But, once you get into Boston, they're less supportive."

Our poll shows that the convention will trigger big changes among commuters, and significantly reduce traffic. When we asked commuters what they'll do during the convention, 28 percent said take a vacation, 25 percent said avoid Boston, 13 percent said work from home and 34 percent work as usual in the city.

"We've learned that two-thirds of regular Boston commuters will not be in Boston come convention time, so the warnings have worked."

If Boston Police hope to build public support for their contract demands, our poll says picketing isn't the way to do it.

Asked whether police should protest during the convention, only 28 percent said yes, 65 percent no.

Professor David Paleologos, Suffolk University Pollster
"Respondents clearly do not want the police to protest, overwhelmingly. But if they do protest, respondents are split in terms of whether the police should get what they're asking for or get less."

And our poll also shows Boston Mayor Tom Menino is the man in the middle of it all. Among all politicians, he has the most to gain or lose, and his legacy is on the line.

"If this convention is a success, it's his baby and, if it's a failure, unfortunately, it's his baby as well. The responsibility for the convention falls on Tom Menino's shoulders."

We also found more voters think the city will lose money, not make it, on the convention and that by a two to one margin, they are not concerned about a terrorist attack.

But there's obviously uncertainty. When we asked, "if we had to do it again, do you think Boston would want this convention?" 43 percent said yes, 42 percent no. Now that's too close to call.
