Earlier polls had voters squarely opposed to the new stadium for the Arizona Cardinals, but the latest poll indicates its dead heat between those who oppose and favor Proposition 302. Results from a phone poll of 588 Maricopa County voters showed that 46 percent oppose the plan, while 44 percent favor it. An additional 10% are undecided.

Proposition 302 would add new taxes to hotel rooms and rental cars to fund a new stadium, for Cactus League expansion, youth and amateur sports facilities and more tourism funds. The Arizona Cardinals and the National Football League would contribute $85 million toward the cost of building the stadium.

A number of communities have offered potential sites for the stadium, if the proposition passes. The suburbs of Tempe and Mesa want to locate it on a joint parcel between the two cities, and more than a dozen West Valley cities have banded together to offer a site of their own. The stadium would require an estimated $100-million investment in infrastructure development, a cost that would be borne by the host community.
