There is a story this morning in the NJ Star-Ledger County News section, front page below the fold, on this gargabe. The headline attributes these fliers to a "Supremacist group" later identified as that same "The League of American Patriots" listed on the flier at the link you posted.
The Star-Ledger doesn't have a link for this story at their site but their sister paper on NJ.com in Morristown does.

Some neighborhoods in Roxbury were blanketed over the weekend with campaign literature from a white supremacist, anti-immigration group that bluntly raised the issue of race regarding presidential candidate Barack Obama, offending some recipients and angering Democratic leaders.
A flier left on driveways in a neatly packaged plastic envelope and distributed by a group named the League of American Patriots, with a Butler mailing address, questioned, "Do You Want A Black President?" and stated "Black Ruled Nations most unstable and violent in the world."
Police said they received some complaint calls Saturday about the flier and were reviewing the issue to determine if there were any illegalities connected to the material or its distribution.
"I think whoever is doing this should stop and just deal solely with the facts and issues involved in this election," said Morris County Democratic Party Chairman Lewis Candura, who was notified "racist materials" were being distributed.

Attempts to reach the League of American Patriots, by telephone and e-mail, were unsuccessful yesterday. There were no names of group leaders or organizers on the flier or the group's website.
Corsetto, a former school board president in Dover, said she was shocked to get the flier.
"I'm not against free speech, but I was shocked to find stuff like this in my neighborhood," Corsetto said. "I know racism is out there in this world, but I'm particularly disturbed to believe this is happening in Morris County."
The League of American Patriots was formed March 29 at a meeting attended by more than 20 people at an undisclosed site in northern New Jersey, followed by a July meeting at an undisclosed Morris County park, according to the organization's website.
The group is "committed to restoring America to the principles upon which it was founded. First and foremost is halting the rapid demographic decline of the European peoples in our homeland," according to the website. League members attended an immigration reform rally in Lakewood in May and what was billed as an anti-Mexican rally in Shenandoah, Pa., in August, according to the site.
