2012 presidential candidates burst into song

The current crop of presidential candidates can't seem to stop singing on the campaign trail.

Amid the uncertainty of the race for the White House one thing is apparent: No one is winning any awards for their musical skills.

So far, Mitt Romney has already serenaded three separate audiences, twice bursting into the patriotic ode "America the Beautiful" and belting out "Happy Birthday" to South Carolina Gov. Nikki Haley (R).

Romney's GOP rival Newt Gingrich was also caught singing "Happy Birthday" during the Lincoln Day Dinner in West Palm Beach on Saturday.

President Barack Obama showed audiences the power of a smooth falsetto. He quietly crooned Al Green's "Let's Stay Together" during a stop at the Apollo Theatre in late January.

The president is also the only candidate to have won a Grammy — though not for his musical talents. Obama took home the award in 2008 in the best spoken word category for the audio version of his book "The Audacity of Hope: Thoughts on Reclaiming the American Dream."

But 2012 isn't the only election year where presidential candidates were caught singing. The last presidential election cycle saw the likes of then Sen. Hillary Clinton (D-N.Y.), Sen. John McCain (R-Ariz.) and GOP hopeful Alan Keyes trying to hit the high notes on the stump.
