When will the discussion over lack of affordable housing begin to shift to the real problem, the urban growth boundary?   BTW this also is a primary contributing factor to gridlock.  Oregon is as big as Pennsylvania and Ohio combined, yet we have given in to a solution that we must all live in a shoebox.  There are thousands of square miles around Portland that could be developed, and developed with harmony in the environment.  The political power of Metro and urban developers is undermining our quality of life.  Being progressive might mean to look at other alternatives, rather than trying to fix problems with the wrong tools.
