Truth in advertising

We have an Advertising Standards Authority, whose remit is to ensure that ads are legal, decent, honest and truthful.

"before distributing or submitting a marketing communication for publication, marketers must hold documentary evidence to prove all claims, whether direct or implied, that are capable of objective substantiation"

If you make a claim, you should be able to show that it's true.

But. I see so many advertising claims about god. How do they get away with that?

And in relation to current events, "we do not have remit over non-broadcast ads where the purpose of the ad is to persuade voters in a local, national or international electoral referendum"

This is a huge, gaping hole, in an area of life more important than cosmetics or travel. Wouldn't it be great of politicians were held to the same standards that we apply to mascara?
