President Obama’s budget doesn’t have enough support from lawmakers to pass, the Senate Budget Committee chairman said Tuesday. Sen. Kent Conrad (D-N.D.) said he has spoken to enough colleagues about several different provisions in the budget request to make him think Congress won’t pass it. Conrad urged White House budget director Peter Orszag not to “draw lines in the sand” with lawmakers, most notably on Obama’s plan for a cap-and-trade system to curb carbon emissions. “Anybody who thinks it will be easy to get the votes on the budget in the conditions that we face is smoking something,” Conrad said.
