Sacramento’s arena war hit new levels of intensity this week after Seattle financier Chris Hansen was revealed as the secret source of money for a petition drive to put the city’s arena plans to a public vote.

Seizing on outrage at the news, arena supporters took to the streets Saturday, hanging more than 1,000 fliers on front doors asking residents who signed the petitions to withdraw their signatures. “Don’t let Seattle money steal away our chance at 4,000 jobs for Sacramento!” the fliers urged.

Arena backers, a group that includes many of the city’s prominent business people and politicians, argue the Seattle funding offers proof that the two-month-old petition drive is really an attempt to derail the city’s downtown arena plans and push the Kings out of town.

Yet Sacramento Taxpayers Opposed to Pork, the group behind the ballot measure, insists it is a homegrown effort, aimed at giving voters a voice. Its leaders today vowed to come back fighting - possibly with a local fundraising effort.
