There's something about President Obama's rallies that just knock people off their feet. Since 2008, people have been fainting during Obama's speeches, and the spells continue. At least one woman fainted during the president's speech at Prince George's Community College in Largo, Maryland, on Thursday--the third such incident this month. Someone passed out watching the president's speech at a Daimler plant in North Carolina last week, as did a rallygoer in Nashua, New Hampshire, the week before. All three of the people who fainted this month were reportedly women and, while the cause is unclear, Obama is used to it. "Folks do this all the time at my meetings," he said in Nashua. "You have to eat ahead of time to keep your blood sugar up."
