J.D. Hayworth is throwing a birthday party for Joe Arpaio, the controversial Maricopa County sheriff, as a way to bolster his stuttering Senate campaign.

Hayworth is selling tickets to the anti-illegal immigration advocate's "biggest best dang birthday dash" in order to raise money for his bid to unseat Sen. John McCain (R-Ariz.).

"Sheriff Joe has been a wonderful public servant and a great friend of my campaign," Hayworth said in a statement. The even takes place Saturday at the Silver Spur Saloon and Eatery in Cave Creek, north of Phoenix.

Hayworth's campaign has been struggling to fundraise. Earlier this week, it fell some $5,000 short of its goal of raising $800,000 in a "money bomb."

Moreover, Hayworth was passed over by the group Tea Party Express as it made another round of endorsements this week. The former congressman did, however, get the backing of the local North Phoenix Tea Party.

For his part Arpaio, has become a kind of novelty fundraiser. In April, Arizona House candidate Vernon Parker (R) offered supporters a bus trip to the border with the sheriff at the cost of $200 per person.
