The White House on Tuesday panned the release of the Republican budget plan, saying the blueprint outlined by Wisconsin Rep. Paul Ryan “doesn’t add up.”

“Deficit reduction that asks nothing from the wealthiest Americans has serious consequences for the middle class,” White House Press Secretary Jay Carney said in a statement. “By choosing to give the wealthiest Americans a new tax cut, this budget as written will either fail to achieve any meaningful deficit reduction, raise taxes on middle class families by more than $2,000 — or both.”

Unlike most years, the Ryan plan represents the opening salvo in budget negotiations between the White House and Congress. Obama won’t release his budget until April 8, according to congressional sources, more than two months after the statutory deadline.

Ryan’s plan calls for the repeal of Obamacare and a balanced budget within 10 years. Obama is essentially relaunching the attack he made against Ryan during the presidential campaign, dismissing his fiscal approach as one that protects the wealthy at the expense of the middle class.

“The president still believes it is the wrong course for America,” Carney said. “That’s why the president has put forward a balanced approach to deficit reduction with no sacred cows.”

Unlike Ryan’s plan, however, Obama’s yet-to-be released blueprint won’t call for a balanced budget. Republicans mocked that assertion Tuesday, saying it proved Obama was not committed to stemming a tide of red ink.

Obama will travel to Capitol Hill Tuesday afternoon to meet with Senate Democrats, launching a three-day blitz to win over lawmakers on his plan for a “grand bargain” on deficit reduction.
