This better not be about an exploratory committee.

Sierra club leader Mike McGinn, who's been hinting for a few months now that he might take on Mayor Greg Nickels (and who did a poll on Nickels this month, according to a green lobbyist I just talked to) is making an announcement at Piecora's Pizza on Capitol Hill tomorrow. 

I just called McGinn to see if I could get a sneak preview. Answering machine. 

Here's the press release that went out this afternoon:
