Young Conservatives for the Freedom to Marry and Log Cabin Republicans will be running the above full-page ad (click to enlarge) in Wednesday’s Tampa Tribune calling on the GOP to support the freedom to marry for gay and lesbian couples.

Yesterday, the Human Rights Campaign and Freedom to Marry teamed to air an ad on TV featuring San Diego’s Republican Mayor Jerry Sanders arguing the case for marriage equality. Find the video here.

The full-page color ad features photos of same-sex couples and their families. It emphasizes that the freedom to marry is fully consistent with principles valued by conservatives — freedom, personal responsibility and the importance of family.

An email from Log Cabin Republicans said the ad comes in the wake of the party’s extreme stance on marriage in its draft platform, which includes support for a federal constitutional amendment banning the freedom to marry for same-sex couples. Tony Perkins, the president of the anti-gay Family Research Council, authored the marriage plank, which is expected to be ratified at the convention.

“Gay or straight, Republicans are united in the belief that strong families are critical to a free society,” said R. Clarke Cooper, executive director of Log Cabin Republicans. “As fellow conservatives, Log Cabin Republicans actually agree with Tony Perkins about the importance of family values. The difference is, we believe that the freedom to marry is directly in line with the core ideals and principles of the Republican Party — less government, more individual freedom, personal responsibility and the importance of family.”
