And yes, if humanly possible, Dan Savage is planning on attending. This could get interesting!

UPDATE! Bit more info on tomorrow's rally:

Rally in Support of Sam Adams, Mayor of Portland

When: Friday, January 23th, 5:30pm

Where: Portland City Hall

Who: Sam Adams supporters who feel that his two decades of committed service to the city of Portland by far outweigh his honesty about the details of his (legal and consensual) sex life. Our trust is not broken because he made a mistake when cornered with an inappropriate question.

And Dan Savage sez with authority: I'M GOING TO BE THERE.
