Teen Sex Education

I'm working on something that had me looking up papers on sex education and I came across this article. The following quote made me think about something I'd not thought of before:

"The White House is pouring money into programs that tell teens to just say no to sex. Most experts say the programs don't work -- except to enrich the religious right."

Why politically support faith-based programs if they aren't anymore effective than secular ones (and in the case of abstinence, the evidence is weak that they work at all)? It might make sense if they are meant to reward one's political base - a kind of rent-seeking by religious organizations?
