Chris Cillizza of the Washington Post's  "The Fix" political blog, notes R.T. Rybak's filing for governor with a bit of praise:

Minneapolis Mayor R.T. Rybak filed for governor Thursday, giving Democrats their strongest candidate to date in the 2010 Minnesota governor's race. In an e-mail to supporters about his decision, Rybak said his travels across the state convinced him that Minnesotans were "looking for leadership focused on more jobs, better schools and affordable health care." Rybak joins a very crowded Democratic field that includes seven other candidates seeking to replace Gov. Tim Pawlenty (R). Seven Republicans are running for the Republican nod with an eighth -- former senator Norm Coleman -- considering the contest but not likely to decide until next year. The Minnesota governorship is seen as a ripe pickup opportunity for Democrats given the state's progressive leanings.
