(CNN) A new super PAC plans to spend $1 million to help Cory Booker as he struggles to gain traction in the Democratic race for president, with the immediate goal of helping the New Jersey Democrat make the cut for the December debate stage.

United We Win, which was formed Wednesday with the backing of New Jersey-based Democratic donors and consultants, "is supported by individuals who know Cory and have seen the transformative impact that has been made by his leadership and dedication to doing what's right, from Newark to Washington," said Philip Swibinski, a spokesperson for the group.

The super PAC made a splash Thursday with an initial digital ad buy of more than $154,000 nationally. The group plans to spend $1 million over the next month, Swibinski said, with digital ads geared toward attracting small-dollar donors to help Booker meet the DNC's threshold for the next debate.

"That's what we're laser-focused on right now," Swibinski said.

That goal seems well within reach. According to Booker's campaign, he needs fewer than 15,000 donors to meet the higher 200,000 donor mark for the December debate.
