Rocker Jon Bon Jovi is urging friend and former U.S. Vice President Al Gore to enter the battle for the White House, but he is not hopeful. The Livin' on a Prayer hitmaker, who supported Gore on an election trail in 2000, thinks his friend will make a good president - but says it is unlikely Gore will join the race for the top job in Washington. He says, "I think the needle is closer to an absolute 'No' than it is to a 'Yes'. That is the way to phrase it best, and I talk to him a lot."
