Those shares were worth about $9.8 billion as of Monday. That would leave taxpayers with a loss of $16.6 billion.

But that‘s not the full tally. Obama let GM keep $45 billion in past losses to offset future profits. Those are usually wiped out or slashed, along with debts, in bankruptcy. But the administration essentially gifted $45 billion in write-offs (book value $18 billion) to GM. So when GM earned a $7.6 billion profit in 2011 (more on that below), it paid no taxes.
