The arena had to raise the music volume to drown out the booing. Some have claimed they also piped in cheers. Awesome. Notice the Obama/Biden signs at the 44-second mark. Big thanks to whoever that is holding them. I guess Pennsylvania isn't a swing state anymore. Update: Palin has said she put her 7-year-old daughter Piper in a Flyers jersey to discourage some of the booing. Wow.
