Secular Americans aren't an organized lot with a clear political agenda. Unlike religious voters whose convictions often determine their political choices, people are identified by the lack of something — belief in God, faith in Jesus, interest in church. That doesn't always translate into a predictable voting strategy.
In the swing state of Colorado, for example, secular women who favor abortion rights might not vote for Obama because other issues could be of greater concern to them, such as the economy.
While a few organizations, for example the Freedom From Religion Foundation and the American Humanist Association, provide support to the nonreligious, there is nothing on the secular left akin to the hundred-million-dollar media empires and multimillion-dollar PACs of the religious right. Thousands of state and national legislators don't owe their jobs to secularists.
But if the rise of the "nones" keeps up the pace it is making now, who knows what will happen.
