The Presidential Memorial Commission of San Francisco (Presidential Memorial Commission for short) was a voter group that sponsored a satirical but real 2008 ballot initiative to rename the Oceanside Water Pollution Control Plant, a wastewater treatment plant in San Francisco, California, after outgoing Republican U.S. President George W. Bush. The resulting proposed ordinance, Proposition R, would have taken effect immediately upon the inauguration of Bush's successor if passed. It was, however, voted down decisively in the November 2008 San Francisco general election, with "no" votes outnumbering "yes" votes by a margin of more than two-to-one.
