Obama's money

Democratic presidential candidate Barack Obama wants to raises taxes on the wealthy, but as a member of that social class, he isn't eager to fall victim himself. He has invested at least $1 million in a fund that yields tax-free income.

The Illinois senator's latest campaign-finance disclosure shows that his investments have nearly tripled in the past two years to as much as $7.4 million, and his income in 2007 surged past $4 million, not counting his government salary.

Obama reported accounts with Morgan Chase Private Client Asset Management, an elite firm that deals only with the rich, as well as a host of retirement accounts, some in the name of his wife, Michelle.

Because the required disclosure forms allow candidates to report their assets in ranges, such as $250,001 to $500,000, Obama's net worth at the end of 2007 -- not including his home and other nonfinancial assets -- was pegged between $2,022,016 and $7,356,000.

By far the largest account, valued between $1 million and $5 million, was in the Northern Municipal Money Market Fund. It generated tax-free interest in 2007 of between $15,001 and $50,000.
