Madonna kicked off her "Sticky and Sweet" tour this week and used the opportunity to make a clear statement for who she wants to win the U.S. presidency.

In one of her concert acts, a video was displayed showing images of destruction, global warming, Nazi dictator Adolf Hitler, Zimbabwe's authoritarian President Robert Mugabe, and most importantly, the U.S. Senator, John McCain.

Later on in that act, a video showed images of John Lennon, Al Gore, Mahatma Gandhi and... you guessed it, Barack Obama.

I think celebs are taking it really seriously for this year's election. Associating John McCain with figures like Hitler is a bit much, don't you think?
