It's SayNo2. It's referring to Amendment 2, the November referendum that would place a prohibition against same-sex marriages and possibly even civil union benefits for heterosexual partners into the Florida Constitution. From announcement to supporters:

We hope SayNo2 will be easy to remember and reinforce how dangerous Amendment 2 is to all Floridians. With SayNo2, our message will be simple:

Say No 2 taking away existing benefits and legal protections.

Say No 2 hurting Florida’s seniors who are unmarried by choice.

Say No 2 eliminating shared health care and pension benefits.

Say No 2 someone else deciding who can visit you in the hospital.

Say No 2 more government intrusion into our private lives.

With a new name comes a new Internet home: www.SayNo2.com.

Visitors to www.SayNo2.com will find an expanding and welcoming resource on the “marriage protection” amendment, including facts and stats on the amendment and the campaign, the experience of other states, how to get involved, how to contribute, and media resources – including the nine major newspapers in Florida that have already opposed the amendment.

SayNo2's strategy mirrors the strategy of the only effort that turned back the anti-gay marriage forces, in a Nov. 2006 vote in Arizona, by appealing to straights and gays alike with the dangers of a constitutional provision such as Amendment 2.

Florida Red and Blue is one of two major groups fighting against Amendment 2, with Fairness for All Families being the other. Its current logo is below.
