I actually wish that Huey Lewis had done more to lobby for Kerry. He'd already suffered the negative consequences of having made the public endorsement, but arguably he didn't reap the full benefit he might have been able to achieve.
I wouldn't suggest that people vote based only on a celebrity endorsement, no matter how much they admire the celebrity. But as an opinion of someone whom you respect, I think it's worth considering. When certain fans said that Huey had no business endorsing a politician because he was "just a singer" I think they demeaned their own appreciation of him, robbing him of the esteem that might justify their own (sometimes tremendous) interest in his career. (In other words, what does it say about you if you spend all this emotional energy following someone too vapid to have intelligent opinions about important things?)
But the main reason I think Huey should have done more is the same reason I think everyone should have done more. Sitting on the sidelines when something of this importance is at stake is not good. This election is about a presidency that has defied the principles of freedom establishing it, that has thumbed its nose at the very premise of international cooperation, that has further subordinated the interests of individual citizens to those few who own corporations. The very future of America is at stake, and all who have a vested interest in it are entitled to, and should be, involved in shaping it.
