PAUL KANGAS: House Democrats passed a budget today that reaches balance, but only if President Bush's tax cuts are allowed to expire in 2011. The $2.9 trillion spending blueprint would eventually yield a surplus. But as Darren Gersh reports, the question of exactly how Democrats would put the budget into the black remains to be answered.
