Who offers the best progressive political calendar?

I'm searching for a site with a closely-maintained calendar of upcoming political events relevant to progressive activists.
It should include: key votes in Congress, hearings, trials, protest marches and actions, etc.

Ideally the site would offer an RSS feed.

1. I would have suggested starting up a wiki

But you gotta know that would be vandalized and hacked to death within minutes. :shrug:

2. are we empty-handed ?? I'm surprised.

This post has been up all day on three boards and not one site has been suggested. It's hard to believe that such a basic and essential tool as a progressive activism calendar does not exist. If not, we've got to create one.
