The Matthew 25 Network, a Christian political group that endorsed Barack ObamaBarack Hussein ObamaTrump keeps Obama immigration program, and Democrats blast him The House Judiciary Committee's fundamental choice Teaching black children to read is an act of social justice MORE in May, is out with a new radio ad supporting the Democrat's run at the White House.

The group has been airing ads in support of Obama since July.

The latest ad will air on Christian radio stations in battleground states. It tells listeners that Christian faith is the source of Obama's message of hope.

The group says it will spend about $15,000 airing ads for Obama between now and Nov. 4; a Matthew 25 spokesman noted that air time on Christian radio stations is relatively cheap, hinting that the $15,000 will go a longer way than other groups' cash.
