Marc Cenedella, Republican Criticized Over Blog, Decides Against Senate Run Marc Cenedella, a wealthy Republican businessman who was laying the groundwork for a United States Senate campaign in New York, announced on Tuesday that he had decided not to run. The announcement came after Mr. Cenedella faced a torrent of criticism over a blog under his name that had entries containing observations about sex, women and drugs. In recent months, Mr. Cenedella had been traveling across the state trying to build support for a campaign to be the Republican nominee to take on Senator Kirsten E. Gillibrand, a first-term Democrat. Mr. Cenedella, 41, the founder of TheLadders.com, a job-search Web site, excited party officials and donors with his Ivy League background, his success in building a business and his promise to tap his wealth in the race. But last week, The New York Times reported that, until recently, blog entries with titles like "Sexy vs. Skanky," "Dating Advice for Girly Girls," "He Stole My Weed" and "High Quality Dope" were on a Web site that bore his photograph and the title "The personal blog of Marc Cenedella." In an entry titled "A New Holiday for Men," there was a link to a separate site that designates March 14 as a special day on which women are encouraged to offer steak and oral sex "to show your man how much you care for him." Another entry linked to a site that purports to provide biblical justification for a man's having more than one wife. "I wasn't so sure about all this Bible stuff," the entry accompanying the link said, "but I'm starting to cotton to it." After the report in The Times, Mr. Cenedella was harshly criticized, particularly by women's groups like Emily's List, which supports female candidates. In a statement released on Tuesday evening, Mr. Cenedella said he had decided against running after concluding that the political calendar was too compressed at this point for him to mount a bid. He also lashed out at Ms. Gillibrand, whom he accused of being behind the report about the blog entries. "Her early and unfounded attacks on me, her weak poll numbers and her lethargic quarterly fund-raising results all point to a politician in trouble," he said. Initially, Mr. Cenedella's representatives would not answer directly when asked repeatedly whether Mr. Cenedella had posted the entries or the links. Instead, his company issued a statement saying that the blog was a maintenance staging site set up at blog.theladders.com/rock that contained testing content from several sources, including spam. Later, an adviser to Mr. Cenedella said the entries were from a site that Mr. Cenedella previously published called Stone, which the adviser said had several authors.
