Municipal elections in Minnesota are nonpartisan, although candidates are able to identify with a political party on the ballot. The 2010 Toronto mayoral election was held on October 25, 2010 to elect a mayor of the city of Toronto, Ontario, Canada.  The mayor's seat was open for the first time since the 2003 Toronto election due to the announcement by incumbent mayor David Miller that he would not seek a third term in office.  The nomination period for the 2010 municipal election opened on January 4, 2010 and closed on September 10, 2010.  The result of the election was a victory for former city councillor Rob Ford.  He received 47% of the vote. The Houston Mayoral Election of 2009 took place on November 3, 2009, to elect the successor to incumbent Mayor Bill White.  White was ineligible for re-election, having served three terms.  The race is officially nonpartisan.  After no candidate received a majority of the votes, the top two candidates - City Controller Annise Parker and former City Attorney Gene Locke - faced each other in a runoff election on December 12, 2009.  On November 11, councilman Peter Brown (who finished third in the first round) publicly endorsed Parker in the Mayor's race.  Annise Parker won the run-off and is now the mayor of Houston. Raymond Thomas "R. T." Rybak Jr. (born November 12, 1955) is an American politician, journalist, businessperson, and activist who served as the 46th mayor of Minneapolis.  In the 2001 election Rybak defeated incumbent Sharon Sayles Belton by a margin of 65% to 35%; the widest margin in city history for a challenge to an incumbent.  He took office in January 2002, and won a second term in November 2005 and a third in November 2009.  In late December 2012, he announced he would not run for another term and was going to be concentrating on his family.  Rybak called being mayor his "dream job." The 2007 Philadelphia mayoral election was held on November 6, 2007 when Philadelphia, Pennsylvania, United States elected Michael Nutter as the Mayor of Philadelphia starting in 2008.  The incumbent mayor, John F. Street was barred from seeking a third term because of term limits.  The Democratic Party primary campaign saw two well-known, well-funded Philadelphia congressmen – Bob Brady and Chaka Fattah – eclipsed by self-funding businessman Tom Knox and reformist former Philadelphia City Council member Nutter, who won by a surprisingly large margin in the primary election on May 15.  He went on to face Republican Party nominee Al Taubenberger in the general election, which he won by a large margin and with the lowest voter turnout in a Philadelphia mayoral election without an incumbent since 1951.  Mayor Nutter was sworn in on January 7, 2008. The 2009 Minneapolis mayoral election was held on November 3, 2009 to elect the Mayor of Minneapolis for a four-year term.  Incumbent R. T.
