First Lady Michelle Obama was booed at a NASCAR event on Sunday.

Obama, Dr. Jill Biden (wife of Vice President Joe Biden), and Iraqi army veteran Sgt. Andrew Berry and his family were set to commence the finale of the 2011 NASCAR Sprint Cup Series.  

As soon as First Lady Obama and Dr. Biden were introduced, however, the crowd at Homestead-Miami Speedway greeted them with audible boos, which seemed to drown out (judging by the video below) whatever applause they received.

(White House officials, however, claim there were more cheers than boos, according to USA Today.)

Sgt. Berry, meanwhile, received a smattering of applause.  

First Lady Obama, Sgt. Berry, and Dr. Biden were there to support Joining Forces – a national initiative to promote employment and education opportunities for veterans – at the Sunday NASCAR event.

More than two years after the Great Recession ended, many American are still struggling as the unemployment rate has remained stubbornly around 9 percent.  Some of them blame politicians like President Barack Obama.

Obama, however, is not the only one taking heat from the American public; the approval rating of Congress is at 9 percent, according to a recent CBS poll.  

Michelle Obama’s rating is at a relatively high 63 percent.  Historically, First Ladies usually enjoy high approval ratings.  

Laura Bush, for example, maintained a very high approval rating (as high as 82 percent) even as her husband President George W. Bush’s approval rating dipped in the 20s.

Still, First Lady Obama was booed by the Florida NASCAR crowd on Sunday, which was likely predominately Republican.

This is not the first time the First Lady has received such treatment.  She was booed in Nevada, Missouri, and perhaps even in New York.

Contrastingly, there are little or no documented instances of former First Lady Laura Bush being publicly booed.
