Steven Greenhouse, the Times's pro-union, anti-Wal-Mart labor reporter, seemed pretty enthused about the A.F.L.-C.I.O.'s attack mailings against John McCain in "A.F.L.-C.I.O. Targets Seniors," the neutrally headlined story he filed to the "Caucus" blog Tuesday morning. In contrast, another Times reporter, Damien Cave, was offended at the sight of two anti-Obama mailers in his Florida mailbox that dared to attack Obama on taxes and crime. Only two of the 19 paragraphs of Greenhouse's story are devoted to (very mildly) fact-checking the false claims from the union-backed mailing. Here's an excerpt:

The latest mailer is headlined, "John McCain: A Disaster for Retirees." It criticizes his proposal for partially privatizing Social Security, saying, "This risky move will jeopardize the chances of a secure retirement for millions of Americans."The mailer also seeks to undermine the Republican candidate by saying, "McCain will cut Medicare." It says he "wants to fund his pro-insurance company health care plan by taking more than $1 trillion from Medicare."
