Politico's Jonathan Martin and RCP's Tom Bevan are talking about rumors that have influential Christian conservative leader James Dobson set to announce his presidential endorsement in a matter of days. The candidate he's picked, per reports: Mike Huckabee.

One Christian conservative activist close to both men suggests Dobson's endorsement is made all the more likely after Don Wildmon, the head of the American Family Association and chairman of the influential Arlington Group, announced he would back Huckabee today. The source says Wildmon and Dobson reflect each other's thinking, and that "they both realize that their support, if combined, will be a sum greater than its parts."

Dobson would bring Huckabee a bigger name than Wildmon, and would certainly drive a significant amount of mainstream media coverage. But in practical terms, the AFA probably has the wider reach, with an email list of over 3.3 million people. Together, the two would give Huckabee the following among Christian conservatives that he has lacked thus far, to the surprise of many, as movement leaders have chosen to side with other candidates with better poll numbers over the more ideologically similar Huckabee.

Update: Dobson is pushing back on the idea that an endorsement is imminent, or even that an endorsement would favor Huckabee, according to Paul Weyrich, "in ferocious terms," according to National Journal's Linda Douglass.
