The Romneys celebrate 43 years of marriage.

As Mitt Romney himself tweeted this morning, it's an exciting day in the Romney household: Mitt just won the Illinois primary, Jeb Bush just endorsed him, it's son Tagg's birthday, and it's Mitt and Ann's 43rd wedding anniversary. To mark the event, the campaign posted this adorable wedding photo on Facebook. Seeing the couple today, it's heartwarming to see how in love they remain (and how well they've both aged -- we should all be so lucky).

The campaign also released a video called "The Love Story Continues." It goes without saying that Romney's strong marriage is an asset politically, helping to burnish his social conservative values, and perhaps appeal to women -- or at the very least not repel them as his rival Newt Gingrich has done.
