Judi Giuliani may go to cabinet meetings, but Mitt Romney says his wife's positions "are not terrible relevant to my campaign." At least, they're not after it comes out that she gave money to Planned Parenthood.
Of course, when the Romney campaign wants to trot Ann out as a symbol of how good a husband Mitt is (as opposed to some other candidates, ahem), she's quite relevant.
And, this certainly isn't the story about Ann's political influence the campaign has told before, as Red State points out.
