Where can I watch the DNC Thursday night for free in San Francisco?

My friend asked me this earlier and I thought it was a good question for fluther. (Don’t worry—I will try to sign her up!) She particularly wanted to go somewhere downtown/ financial district. Are there any bars or nerdy meet ups happening? I watched it at the Plough and Stars 4 years ago at a Howard Dean meet-up. I am from Vermont, so I loved those Dean meet-ups!
