SEATTLE -

Several high-profile challengers are hoping to make Mike McGinn the second straight Seattle mayor to be ousted in the primary election.

State Sen. Ed Murray, City Councilman Bruce Harrell and former City Councilman Peter Steinbrueck are among the candidates voters are choosing from Tuesday.  McGinn's opponents say his governing style is divisive and that McGinn has alienated business groups and the state Legislature.

McGinn, an attorney and former Sierra Club leader, points to the city's improving economy, increased spending on education programs and his support for more transit options.

The top two finishers in the primary advance to the general election. McGinn's predecessor, Greg Nickels, finished third in the 2009 primary.
