People in my opinion, should avoid using the platform they are given for one thing, and using it to influence another. In other words, Bill Clinton should have enough character to not use his position as former president of the USA to get a high profile gig playing saxophone for a major touring band anymore than Madonna should use her platform she has earned by writing crappy pop music to get people to vote for her choice.
This event leads me to make a highly peculiar conclusion.
That Bill Clinton has more character than Madonna.
Also, that South Park, as it so often does, really nails it with near supernatural insight.
FOX News:

NEW ORLEANS – Madonna drew boos and triggered a walkout by several concertgoers after she touted President Barack Obama on her “MDNA Tour” in New Orleans.
The Material Girl asked during Saturday night’s performance: “Who’s registered to vote?” She added: “I don’t care who you vote for as long as you vote for Obama.”
What a twat
And has anyone seen her lately? All sinue and botox, eerrrr
It’s sad when misinformed celebs spout political bullshit. She’s an idiot. It’s all about fashion. She goes round the World adopting Black kids as if she’s some great Messiah, she claims she’s Jewish because she follows some heretical Jewish offshoot, and now she’s telling people to vote for some seditious cretin.
Go back to mindless tacky pop Madonna, you may not be very good at it, but it’s still what you’re best at!
No thanks Madonna, I’ll happily stick with Kate Bush and vote for the Mormon, not the Muslim.
I’m surprised she didn’t strip for Obama.
She has always made my skin crawl.
She has never been a rational person.
DP I think she said that if Obama is re-elected she will strip.
That DP, is the single best reason to vote for Romney I have heard yet. Think of the number of men not currently sure of their orientation that will run screaming to the gay side if they got a look at Madonna naked. For the love of the future of the human race vote Romney and prevent a naked Madonna.
Hell that should be Romney’s campaign slogan.
