The Federal Election Commission decided yesterday not to issue an advisory opinion on a request by Sen. John Kerry to use $300,000 of his campaign funds to help finance a documentary about injured veterans from the Iraq War. The question came down to whether the money would be seen as an investment, which is allowed, or operating capital for a business, which is not a permitted use of campaign dollars.

Kerry’s attorney said that he did not know whether the senator would proceed with his movie plans without the FEC’s blessing.

Of course, the other day, the senator from Massachusetts seemed to be leaning toward another entertainment genre—trying his hand at a bit of political humor, a la a particular late-night TV talk show host who’s been in the news lately. “Too bad,’’ Kerry said in reference to the Mark Sanford saga, the day before the governor’s admission of an affair, “if a governor had to go missing it couldn’t have been the governor of Alaska. You know, Sarah Palin.’’
