President Barack Obama outraised GOP presidential nominee Mitt Romney among New Jersey donors by more than $540,000 in the month of August, campaign finance records show.

But despite the heavy Obama lead in the waning days of summer, Romney still holds about a $100,000 lead among Garden State donors despite a recent poll showing the Republican down by 15 points in the state.

In total, Romney has raised $7.1 million in New Jersey against Obama's haul of $7.09 million (including transfers from joint fundraising committees.)

Romney has taken to fundraising via robocall, asking voters for at least a $3 donation in an effort to stem the Obama tide.  As of Aug. 31, the president had outraised Romney nationally $432 million to $274 million and the Romney call beseeches donors to help make the difference.

The calls have reportedly been made to both unaffiliated voters as well as registered Democrats and use "Defeat Obama" as the caller ID name.  A call to the number goes to the "Conservative Majority Fund," a PAC founded in 2012, "to expose Barack Obama and his mysterious past to the American people."  The PAC bills itself as "one of the most aggressive organizations advocating for the defeat of Barack Obama through investigative research, voter education and television ads."

The PAC's website directs visitors to sign a petition to "Demand Congress Investigate Barack Obama’s Forged Birth Certificate."

A search of FEC records show the PAC has spent about $1.5 million on robocalls since Aug. 1, about $45,000 of it in New Jersey.
