Should money market mutual fund providers vote Democratic? We noticed in an Associated Press "Summaries of Senate financial disclosure forms" story that Democratic presidential candidate Barack Obama lists among his major assets $1 million to $5 million in Northern Municipal Money Market Fund. (Obama also lists $500,000-$1 million in U.S. Treasury notes.) The story also notes, "Major sources of unearned income: Interest from money market fund, $15,000-$50,000." Finally, it says of Obama, "He and his wife, Michelle, bought the money market fund in May 2007, then sold off $500,000-$1 million worth on July 26." Money funds were not listed among McCain's holdings, which included $15,000-$50,000 in a "checking account".
