SAN ANTONIO—Spurs center Tim Duncan sent an e-mail message to his fellow NBA players Tuesday volunteering to use his 1992 Buick LeSabre to chauffeur anyone "who needs a ride" to his assigned polling place to vote in the 2008 presidential election. "It's our responsibility to cast that ballot so that our democracy may continue working properly," wrote Duncan, adding that he was confident that every eligible member of the NBA was registered to vote and had been closely following all the 2008 races for months. "There's no need to feel pressure to tell me who you're voting for—that information is between you and the voting machine. All I ask is that you please be at the curb on time, buckle up, and treat my car with respect." According to Duncan, the "huge response" has forced him to schedule two separate trips, which he has detailed in a Google calendar and shared with all participants.
