Is Arnold Schwarzenegger's political fervor rubbing off on fellow celeb Kelsey Grammer? The 48-year-old Frasier star is hinting that when he's done acting, he may run for the U.S. Senate in California. "If you have the good fortune to become wealthy doing what you love to do, what happens is, you now have an obligation to give back in some way," he said on Fox News Channel's Hannity &#038 Colmes. Not just yet, though. Grammer still plans to pursue other acting gigs after wrapping Frasier's final season.
