It’s un-American to be Patriotic — at least when it comes to football.

Just 16 percent of Americans are rooting for the New England Patriots in Sunday’s Super Bowl match-up with the Philadelphia Eagles, according to a Monmouth University Poll. Thirty-seven percent say they’re backing the Eagles, 46 percent say it doesn’t matter and 39 percent just want the Pats to lose.

But many are apparently frightened by Philly fans.

Twenty-six percent polled say they’d be “worried” about encountering Eagles fans in a dark alley.
