According to the most recent Horizon poll from Phoenix' PBS outlet KAET, 57% of Arizonans support the Minuteman Project. 34% were opposed. In less favorable news, 62% support Bush's guest worker plan, and 29% oppose it. Opinions were split on the actions of Patrick Haab.

The report from KAET, with the questions that were askied, is here. AP reports are here and here and a report from Capitol Media Services is here.

Note that KAET is a PBS affiliate and that they did this poll with the Walter Cronkite School of Journalism and Mass Communication at Arizona State University and that they've been doing similar polls on current events for years. I'd be slightly surprised if the usual suspects call the results non-representative.
