A reader of a quarterly magazine published by the city government submitted a letter to the magazine critical of the mayor's dealings with the local business community. The magazine's editor thanked the reader for the letter, but informed her that the magazine would not publish the letter because it was not the magazine's practice to publish letters critical of the mayor. The reader then filed a lawsuit against the city government on the basis of its failure to publish the letter. Would the city government likely succeed in defending the lawsuit?
