Van Tran, who is running against Rep. Loretta Sanchez, sent out a flier to central Orange County voters with the scratch-and-sniff section labeled, "something smells rotten about Loretta," The Orange County Register reported Wednesday.
"It's the stench of Washington," the mailer says.
George Andrews, Tran's campaign manager, said the scratch-and-sniff section is supposed to smell like trash.
Caroline Hogan, a spokeswoman for Sanchez, dismissed the mailer as a cheap gimmick.
"Talk about bad taste. While our opponent is busy spamming voters with ill-smelling mailers, Rep. Sanchez is talking about the issues that matter to Orange County families," Hogan said.
