ST. PAUL, Minn. – Target Corp.’s CEO on Tuesday defended the discount retailer’s political donations to a Minnesota group helping the state’s Republican candidate for governor, telling employees at its Minneapolis headquarters that the company’s support of the gay community is “unwavering.”

Chief Executive Gregg Steinhafel said gay employees have been raising concerns about the money helping state Rep. Tom Emmer, who opposes gay marriage. Target gave $150,000 to MN Forward, a group staffed by former insiders from outgoing Republican Gov. Tim Pawlenty’s administration. MN Forward is running TV ads supporting Emmer.

“We rarely endorse all advocated positions of the organizations or candidates we support, and we do not have a political or social agenda,” Steinhafel said in an e-mail.

He added: “Let me be very clear, Target’s support of the GLBT community is unwavering, and inclusiveness remains a core value of our company.”

Emmer is a conservative who lauds Arizona’s strict approach to illegal immigration, once advocated chemical castration for sex offenders and wants to lower taxes. His profile contrasts with Target’s moderate image in Minnesota, where the company is known for donating to public school programs, food pantries and the annual Twin Cities Gay Pride Festival.

Target donated to MN Forward under new laws allowing corporations to spend company money on election campaigns. Corporate donations have been flowing since the U.S. Supreme Court threw out parts of a 63-year-old law that barred companies and unions from donating to campaigns for or against candidates.

The decision, which came earlier this year, changed rules in about half the states. But the change is so new that experts don’t have a good handle on the likely impact nationally.

In Minnesota, where Target has its headquarters, Democrats are grumbling about the large donation, and some are talking about striking back at the popular brand.

A few voices have even called for a boycott in the state, one of Target’s top three for sales. One Democratic-backed group is reaching out to Target employees through Facebook ads urging them to sign a petition opposing the donations.

“Target is making a huge mistake,” said Laura Hedlund, a former Democratic campaign worker who picketed outside a suburban Minneapolis Target store Saturday, urging shoppers to spend their money elsewhere.

A Target spokeswoman said the company supports causes and candidates “based strictly on issues that affect our retail and business objectives.”

Spokeswoman Lena Michaud said Target has a history of giving in state and local races where allowed, but wouldn’t provide detail on those donations.

She added that TargetCitizens, the company’s federal political action committee, has spread donations evenly between Democrats and Republicans so far this year.

Political action committees contribute money collected from employees and shareholders, not from corporate funds.
