Pretty good opinion piece here, although I disagree with his conclusion about Condi Rice (Coming clean, I would vote for her in a heartbeat if she ran for President).
I think that more than anything, it shows the reasons for the decline in party affiliation by the general public. We, the vast majority, are nothing more than the tools to get to power for both sides. They no longer attempt to inspire, or provide hope or leadership. (Okay, I do believe that Bush is providing leadership, since his poll numbers are so low, but on the other hand, he doesn't have to run again, and can do what he damned well pleases).
And politicians wonder why we are becoming so disconnected from the national parties.
