Once named the most powerful gay man in America by Newsweek, David Mixner is angered by the hands-off approach of President Barack Obama and the Democratic National Committee concerning a failed ballot measure in Maine that would have allowed same-sex couples to marry. He says he's also troubled by Obama not quickly fulfilling his campaign promises regarding rights for gays and lesbians.

Mixner now thinks it's time to use the power of the purse to influence lawmakers.

"How can we allow people to dehumanize our relationships and our very integrity if we give people passes to sit out the battle for our very freedom?" Mixner wrote on his blog Thursday. "No longer are political timelines a reason for delay, no longer are incremental approaches acceptable and no longer can the political process expect us to be patient and wait our turn.

"If we support people who are against full equality, how can we expect others to do differently?" he continued. "No more excuses. Stop it. Close the checkbooks to those who are not fully on our side."
