Newt Gingrich finally promises to be faithful to his wife.

When the Iowa social conservative group The Family Leader unveiled a sweeping pledge on marriage and abortion over the summer, Newt Gingrich was one of the candidates who passed on signing it.

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:

I also pledge to uphold the institution of marriage through personal fidelity to my spouse and respect for the marital bonds of others.

Notice that it doesn’t specify which wife.
