Obama budget plan may limit options

WASHINGTON — President Obama’s budget overtures to Republicans may limit his bargaining power if the GOP ever returns to the negotiating table on a grand deficit-reduction deal.

In essence, Obama’s spending blueprint is a final offer, a no-budge budget whose central elements have failed to persuade Republicans in the past.

With many Democrats balking at what he is already offering, it is not politically feasible for him to offer the GOP anything more.

Puzzled Democrats maintain that Obama not only has given away his leverage, he also has threatened the very identity of his party, which sees Social Security as one of its signature achievements.

What has irked Democrats the most is Obama’s decision to include a significant shift in policy in his $3.8 trillion budget that would alter the government’s calculation of inflation, the Consumer Price Index. If adopted, this new ‘‘chained CPI’’ would change the way the government measures inflation and would slow the rise in Social Security benefits and other programs.

In exchange, Obama is insisting on $580 billion in tax increases on wealthier taxpayers.

The president has offered the benefit cut to Republicans before as part of broad deficit-reduction negotiations, and only in exchange for tax increases the GOP stringently opposes. The White House says the same quid pro quo applies to Obama’s current offer, and chained CPI cannot take effect as a solo measure.

The White House has argued that the inflation proposal in the budget is a response to specific Republican demands during budget talks last year.
