Mitt Romney's oldest son, Tagg Romney, wrote on his Twitter feed Sunday afternoon: "This is my favorite video of the campaign so far."
He added the hashtag #AnnRomney4FirstLady.
The link that Tagg provided sent users to a website independent of the Romney campaign, titled AmericaNeedsMitt.com. It was a video called "Judge a Man by the Woman."
It features photos of Mitt and Ann Romney set to music.
But in the text of the website, under the headline, "You Can Judge Mitt By His Woman -- Ann Romney," there is a paragraph of text at which Tagg Romney may not have looked closely enough. The text is largely harmless until the last line, when it makes an obvious comparison of Ann Romney to Callista Gingrich, Newt Gingrich's third wife after extramarital affairs broke up his first two marriages.
"Do we want, as our First Lady, a woman who raised five wonderful and successful sons, is grandmother to 16 beautiful grand kids, and has always been a paragon of virtue? Or do we want 'the other woman?'" the site reads.
The site is run by Mike Sage, of Wichita Falls, Texas, who lists himself on his Facebook page as an "author, editor, publisher, graphics designer, marketing consultant, broadcaster, conservative political activist, stock market trader, and a big Mitt Romney fan."
Here is the full paragraph from the website:
We produced this video several weeks ago, but it definitely needs to be seen by several million more people before we retire it. It’s important that Americans come to realize that a man and his wife are a team, and the fruits of their partnership will be what they bring to the White House. Do we want, as our First Lady, a woman who raised five wonderful and successful sons, is grandmother to 16 beautiful grand kids, and has always been a paragon of virtue? Or do we want “the other woman?”
Neither the Romney campaign nor the Gingrich campaign immediately returned a request for comment.
