Yeah, I thought that too and Keifer’s dad is even a bigger socialist. But people want to have heros and there is hardly anyone who leans to the right in the media. The divide between fiction and reality can be staggering: where actors play honourable characters or certain types of people and their real life is quite the opposite. That is why they're called actors.
You’re right, Donald Sutherland is a really way over the edge Leftist.
I’m sure that Kiefer Sutherland would just like to throttle the character Jack Bauer, so to speak. However, he’s not SO much of a socialist that he doesn’t “put up with” making lot o’ money playing a character that he do doubt despises.
