That snippet was put out by those infowars assholes who are nothing but a piece the same pile of motherload shit from which was cloned southbeach.
Warden Arena is Rollins College, Winter Park FL (metro-Orlando) where Bill recently stumped for Hillary so that was just some idiot kid trying to excite the troops who were waiting in line to see Bill.
Here's the political stats on the townhttp://www.homefacts.com/politics/Florida/Orange-County/Winter-Park.html
in 2012 they voted 50% blue and 49.1% red
Very possible that half those people were Republicans there out of curiosity or patriotism to see an ex president speak.
To me that vid is less reflective of any Hillary support and more indicative of that cheerleader's bad timing and zero feel for her audience. I'm gonna guess she saw a local news cameraman walk into the room and thought she had the charisma to crank things up. Fail.
