Great Kucinich endorsement from Maxspeak. Here's a selection:
The potential of a ‘radical’ candidate is not to run against Bush or the pragmatic candidates. It is to run against the zeitgeist. The fact is that conventional wisdom changes. We can see it changing now with respect to the Iraq war. A progressive candidate has the vision to stick to principles he or she knows to be right, confident that events will carry opinion towards those conclusions. A progressive candidacy can radicalize the public by speaking truth to power, by advancing positions that are right on the merits but unpopular at the moment.

The power of such a candidacy should not be doubted. Nobody thought Eugene McCarthy had a chance of altering Democratic Party politics, and we know what happened. McCarthy made Kennedy and unmade Lyndon Johnson. Kennedy could have been president. I was around then; trust me, nobody thought that would happen.

Winning or losing, such a candidacy can elevate the Democrats’ prospects. Insofar as that candidacy moves the borders of what is perceived as tenable thinking, all Democrats become more mainstream and Bush becomes more extreme.
