Democrat Darcy Burner is launching her third bid for Congress this morning, this time targeting the 1st Congressional District seat being vacated by Jay Inslee.

Burner made the announcement of her 2012 run this morning on KUOW radio and went live with her campaign web site: www.darcyburner.com

A former Microsoft manager, Burner ran unsuccessfully in 2006 and 2008 against Republican Dave Reichert in the 8th Congressional District.

She has spent the last couple years in Washington D.C. as president and executive director of ProgressiveCongress.org and the Progressive Congress Action Fund.

Burner moved back to her Redmond home earlier this year, triggering speculation about her political plans. She doesn't live inside the current 1st District boundaries, but those lines are being redrawn as a part of the ongoing redistricting process. (And it is legal for any state resident to run for Congress in any district.)

In a video on her campaign web site, Burner referenced the slogan of the Occupy Wall Street protests, saying "we need to send people to Congress who will fight for the 99 percent."

The problem in America, Burner said, is that "we've stopped investing in greatness," blaming a system where "bankers, insurance moguls and oil barons" have rigged the rules to take more than half the nation's wealth.

Burner joins of Democrats already maneuvering to succeed Inslee. They include state legislators Roger Goodman, Marko Liias and Steve Hobbs, former legislator Laura Ruderman, tax attorney Andrew Hughes and tech entrepreneur Darshan Rauniyar.

On the Republican side, business consultant James Watkins is running again. Watkins ran against Inslee in 2010.
