THE nations political divisions have reached into the race track. Some NASCAR fans yesterday booed first lady Michelle Obama and Jill Biden, the wife of Vice President Joe Biden, after they were introduced as grand marshals for the race at Homestead-Miami Speedway. Its hard to gauge the intensity of the critics, as many of the boos were drowned out by a military flyover and other pre-race noise. Mrs Obama and Mrs Biden attended the race to promote their Joining Forces project on behalf of military families. The two women received a warmer reception at the pre-race meeting with NASCAR drivers; the Associated Press reported that they received a standing ovation as Mrs. Obama said the NASCAR has been amazing in terms of its support, not just today but every day, for military families. Meanwhile, opponents of Prime Minister Vladimir Putin on Monday hailed an unprecedented show of public protest after the Russian strongman was loudly booed by the crowd at a no-holds-barred fight night.
