Democratic insiders are speculating about whether Barack Obama and his wife, Michelle, will give each other their famous "fist bump" at the party's national convention next week, when he is scheduled to receive the presidential nomination.
Some party veterans think it's a bad idea. "It's too hip," says one. "It's a young people's thing that will turn off or puzzle older voters," who don't have much affinity for Obama so far.
On the other hand, the fist bump would probably further endear the Illinois senator to his legion of young fans, whom he is counting on to reconfigure the electorate with a high turnout in November. "For those under age 30, it would pay off," says a Democratic pollster, but he adds that it may not go over well with those over 60.
The Obamas caused a stir with their celebratory fist bump at a victory rally in St. Paul, Minn., in June. It was picked up on YouTube and became fodder for endless commentary on cable TV and among bloggers, particularly after a Fox News host asked if the gesture was "a terrorist fist jab."
