Alaska offers Democrats another path to cobbling together the three seats they need to flip control of the Senate if Joe Biden wins the presidential race. And along with races in Kansas, Montana and South Carolina, the Alaska foray represents a major offensive into traditionally red states that are more competitive because of President Donald Trump’s sinking poll numbers.

The new super PAC, North Star, formed earlier this week, according to its Federal Election Commission filing, and went up on air Thursday with its first ad, which hits Sullivan on health care. The amount made it the largest spender on television in the race, though other outside groups have been there earlier.

“I think people were initially skeptical. It’s why we were kind of alone out there in investing in Alaska early on,” said Shaughnessy Naughton, president of 314 Action, a Democratic group that backs candidates with science backgrounds and has spent $2 million to boost Gross, an orthopedic surgeon. “But I think people are seeing it as a real race, and that’s why we are seeing other groups start to come in.”

North Star has apparent ties to national Democrats. Its media buyer, Waterfront Strategies, is used by a handful of major Democratic groups, including Senate Majority PAC, which is run by allies of Minority Leader Chuck Schumer. The super PAC maintains its account with Amalgamated Bank, according to its FEC filing, which is a Washington-based bank used by a wide range of Democratic organizations.

A spokesperson for Senate Majority PAC declined to comment on the group. Emails sent to a Gmail address listed on North Star’s FEC filing did not receive a response. The filing also lists a website that has no contact
