A front-page headline in today's New York Times says, "Parties Differ on Whom Economic Aid Should Help." But the story goes on to say that when a presidential campaign coincides with both a Wall Street crisis and soaring home foreclosures, "traditional ideological battles… become blurred." Barack Obama and Hillary Clinton have unveiled government rescue plans for homeowners at costs of about $30 billion. John McCain says it's "not the duty of government to bail out and reward," but he supports the Federal Reserve's plan to lend banks and investment firms up to $400 billion. Are the parties as different as the rhetoric makes them sound? Why is Wall Street contributing more to Obama and Clinton than McCain?
