The whole thing is divided up into two videos because the first videos I saw only showed the crowds reaction, then I found another one which showed over 4 minutes of sustained insults, birds being flipped and chants against Madonna's initial political rant.
So, first, Madonna's comments asking if the audience is registered to vote, then telling them "I don’t care who you vote for as long as you vote for Obama." (Uploaded on October 28, 2012)
Next video is over 4 minutes of a highly irate crowd, flipping birds at the stage as set up people work and around the 2:25 mark, they start chanting "shame on you" over and over again.

Details from the upload YouTube page:
Madonna insulted and booed by fans at her New Orleans concert which is part of her MDNA Tour.
Madonna has gone great length to support Barack Obama but she was not met with favorable response on Saturday, October 27. The singer slipped in some advice for her audience at her New Orleans concert which is part of her MDNA Tour.
"Who's registered to vote?" she asked the crowd. "I don't care who you vote for as long as you vote for Obama." Some of the audience booed at her and reportedly walked out of her concert. Madonna then added, "Seriously, I don't care who you vote for ...do not take this privilege for granted. Go vote."
Appears the crowd doesn't appreciate being told how they should cast their vote.
