The Matthew 25 Network, a political action group targeting evangelical voters, launched a pro-Obama Christian radio campaign last week in Colorado and several other battleground states.

One of two ads airs a speech by presidential candidate Barack Obama on his Christian faith as a source of hope.

The second, called “Pro-Life, Pro-Obama,” features Catholic legal scholar and Republican Doug Kmiec. He describes Obama, who supports abortion rights, as someone who could nonetheless reduce the number of abortions through his support for prenatal care, maternity leave and adoption.

A majority of white evangelical Christians support Republican Sen. John McCain for president, yet polls show that support is lower and less solid than the 78 percent voting for President Bush in 2004.

A recent Pew Forum poll of white evangelical Protestants’ preferences showed McCain’s support slipping from a high Oct. 9-12 of 74 percent to 65 percent Oct. 23-26.

Obama’s numbers for the same periods climbed from 18 percent to 22 percent.
