In the ad, which has been running all month, the former Air America host andatheist advocate warns listeners of the “intrusions of religion into our secular government” and asks them to join FFRF in the organization's efforts against religion in politics:

I’m Ron Reagan, an unabashed atheist, and I’m alarmed by the intrusions of religion into our secular government. That’s why I’m asking you to join the Freedom From Religion Foundation -- the nation’s largest and most effective organization of atheists and agnostics, working to keep state and church separate. Phone 1-800-335-4021 or visit the Freedom From Religion Foundation at FFRF.ORG. Ron Reagan, lifelong atheist, not afraid of burning in hell.

In 2004, three weeks after his father's death, Reagan told The New York Times that he would be an "unelectable" candidate for president because of his secular affiliations.
