Marylanders for Marriage Equality has rolled out several TV ads featuring former NAACP chairman Julian Bond as well as black pastors who emphasize that state law does not force any church to perform a same sex marriage.
"People are understanding that Question 6 is simple," says Sultan Shakir of Maryland for Marriage Equality. "It's about fairness, it's about equality, and it's about treating all people equally."

Opponents have less ads. Instead, the Maryland Marriage Alliance has launched a grassroots campaign targeting an email list of like-minded voters, pastors and churches.
"We just believe that fundamentally marriage is defined between one man and one woman," says Derek McCoy of Maryland Marriage Alliance. "Marriage is more than about what any two adults want."
Similar to other states, opponents recently released ads claiming that Question 6 could impact school curriculum.
But gay marriage supporters say that's just not true.
"I mean local curriculum is decided by curriculum experts, values are taught at home by parents and that's why the passage of marriage equality has nothing to do with what's taught in schools," says Shakir.
So far, 32 out of 32 states have voted against same sex marriage. But Maryland's democratic politics could make it very favorable terrain.
"It would be a landmark event in gay rights politics because no state has ever passed it at the ballot box," says POLITICO national politics editor Charles Mahtesian.
After election day, advocates on both sides of this issue will turn their attention to the supreme court which will soon decide whether to review California's Prop 8 or the Defense of Marriage Act.
