I think signing pledges is dumb. You either believe in something, or you don’t, and you follow through accordingly.

Signing a pledge means little, if it’s done for political gain.

I think signing pledges is dumb

And an oral pledge ain't worth the paper it's written on..

Politico is spinning this (surprise). The pledge to be faithful to marriage was just one element:

Now, Gingrich has answered the pledge with a lengthy written response, vowing to support a federal marriage amendment, reinstate the Mexico City policy -- and, per the stipulations of The Family Leader pledge, to be faithful to his wife.

But Politico ran with just the one part because it allowed them to create an eyebrow-raiser headline.
