Thought a nasty campaign season couldn't get any worse? Look no further than Buffalo, NY.

A group called the Committee To Save The Erie County Republican Party has reportedly been circulating an incendiary attack ad lambasting a New York lawmaker for his deciding vote to legalize gay marriage in the state last year.

The ad, first reported by Politico, appeared in emails as two separate image attachments -- apparently meant as flip sides of a political mailer -- and accuses New York state Senator Mark Grisanti of exchanging his vote in favor of gay marriage for monetary gain.

One side of the ad reads:

How far will a politician go to get in your pant$?

For his Gay Marriage vote, Mark Grisanti received over $750,000. [The ad contains no evidence to substantiate this claim.]

Sometimes they're political whore$.

The other side:

Make sure your son says, "Thank you, Mark Grisanti"

The ad also features photos of two men arranged in steamy poses, which were reportedly lifted from a gay-porn company called Corbin Fisher. (The full ad is viewable at BuzzFeed.)

Grisanti, a Republican, had previously opposed marriage equality, switching his vote at the last-minute to join three other Republicans in securing legalization's passage. "I cannot deny a person, a human being, a taxpayer, a worker, the people of my district and across this state, the State of New York, and those people who make this the great state that it is the same rights that I have with my wife," the Buffalo-area politician said at the time.
