The advertisement, produced by a Republican group and the anti-gay National Organization for Marriage, claims that Barbara Boxer "doesn't share our values" because she supports civil rights for gays and she opposed immigration reform.
The claim about immigration reform is nothing short of bizarre. Although she favors tough border security, Boxer has long been a champion of paths to citizenship for undocumented workers, guest worker programs, and temporary visas.
Boxer's Latino supporters have called on Fiorina to condemn the Spanish-language advertisement, but so far she's supported it, claiming that Boxer's criticism of a weak guest-worker program in 2007 is equivalent to opposing all immigration reform.
The National Organization for Marriage is notorious in some circles for its misleading advertisements, suspicious financial arrangements, and shady dealings. The hetero-centric group was recently slammed by the Human Rights Campaign for its ties to other anti-gay nonprofits, in violation of IRS rules. It's also under investigation by the Maine Ethics Commission for hiding mandatory campaign information.
