(CNN) – People sure to draw the ire of Philadelphia sports fans: Cowboys players. Supporters of any visiting team. Presidential running mates.
Weeks after Republican VP nominee Sarah Palin got a brutal greeting at the rink, football fans gave a similar reception to Vice President-elect Joe Biden.
As Eagles fans watched their team lose to the New York Giants Sunday night, a shot of Biden on the big screen elicited boos from the notoriously tough home crowd, the Associated Press reports.
Biden sat in Eagles owner Jeffrey Lurie's box, taking in the game during his first weekend off since Tuesday's election.
Sarah Palin was booed when she dropped the puck at the Philadelphia Flyers season opener in October. But Philadelphia is a heavily Democratic city, and Palin is not a Pennsylvania native. (Eagles fans also infamously threw snowballs at Santa Claus at a December 1968 game.)
Born in Scranton and now a resident of nearby Wilmington, Delaware, Biden calls himself an Eagles fan but emphasizes that his wife Jill, raised in the Philadelphia suburbs, is the real fan in the family.
"My wife is a die-hard Eagles fan, so we watch every Eagles game," Biden told reporters during a tour of the Pro Football Hall of Fame in September.
"I'm not allowed to say this," he added, whispering to the reporters, "but I also like the Giants."
So maybe it was the fact that Biden had no real allegiance to either team Sunday night that drew Philadelphians' ire, or perhaps it was simply the risk one takes attending a game in the City of Brotherly Love.
