ST. PAUL, Minn. — Gov. Mark Dayton says a legislative vote on a Minnesota Vikings stadium package has been jeopardized by lingering concerns over sites and financing mechanisms.

The Democrat decided against picking a preferred site Wednesday. He deemed competing plans for Minneapolis and Arden Hills currently inadequate for various reasons.

The Legislature convenes its 2012 session next week and the fate of a new Vikings stadium is expected to be a dominant issue. The team's lease at the Metrodome expired at the end of the just-concluded season.

Dayton says the Arden Hills plan has been stymied by concerns over new taxes and whether a voter referendum would be required. The governor says two Minneapolis sites lack full vetting or wouldn't provide enough return on investment.
