 In Ottawa's 2006 municipal election, newcomer Larry O'Brien defeated former city councillor Alex Munter and then-incumbent Bob Chiarelli in an election largely based on the expansion of Ottawa's light rail transit system.A Léger Marketing poll published by the "Ottawa Sun" on May 26, 2007 put O'Brien's approval ratings at 24%, and reported that if an election were held that day, he and Munter would have been tied with 35% of the vote of those surveyed.Terry Kilrea, who had dropped out of the previous mayoral race on August 30, 2006, accused O'Brien of offering him up to $30,000 and a political appointment if Kilrea would withdraw from that race and support O'Brien.
