That’s why New York City’s Michael Bloomberg and Boston’s Thomas Menino have filmed a gun-control commercial that will air during Sunday’s big game between the New York Giants and the New England Patriots.

“Despite the great rivalry between Boston and New York that will certainly be played out in Technicolor on Sunday, what we wanted to show was that the mayors of both these great cities agree, as most Americans do, that we just need to repair our broken background check system in the United States,” Bloomberg advisor John Feinblatt told WCBS 880 reporter Rich Lamb.

The ad was shot Tuesday and will be shown in the Northeast, not nationally.

It shows the two mayors sitting on a couch as if they’re watching the game. They’re wearing Giants and Patriots jerseys over their shirts and ties.

Bloomberg and Menino are founders of Mayors Against Illegal Guns. The group has pushed for a stronger federal background check system.

Feinblatt says 81 percent of gun owners support universal background checks.
