Michelle Obama is one of the more popular political figures in America, with a late-October Marist poll reporting that 63 percent of respondents said they viewed her favorably. But at NASCAR's Sprint Cup finale at Homestead-Miami Speedway on Sunday, boos rained down on the first lady and Dr. Jill Biden as they ceremonially opened the race. Skip to 1:35 in the video above to hear Obama's name announced.

Maybe the boos were evidence of President Obama's unpopularity -- his approval rating sits at just 45 percent -- or maybe they proved once and for all that NASCAR draws a mostly Republican crowd. According to Marist, the first lady's favorability was more evenly split among Republican respondents, at 42 percent favorable/39 percent unfavorable. Either way, it isn't pretty when the first lady gets booed for a public appearance in support of veterans.
