Many economists say such a one-two punch could send the fragile economy back into recession.GOP aides said their plan is based on one presented by Erskine Bowles, co-chairman of a deficit commission Obama appointed earlier in his term, in testimony to a special deficit "supercommittee" last year â¿¿ in effect a milder version of a 2010 Bowles proposal that caused both GOP and Democratic leaders in Congress to recoil. Unlike Bowles' official 2010 plan, drafted with former GOP Sen. Alan Simpson, the version released Monday drops the earlier endorsement of Obama's proposal to increase tax rates on family income exceeding $250,000 back to Clinton-era levels, with the top rate jumping from 35 percent to 39.6 percent. Bowles, in a statement, said he was flattered but the GOP plan does not represent his proposal. Still, he added, "Every offer put forward brings us closer to a deal, but to reach an agreement, it will be necessary for both sides to move beyond their opening positions." By GOP math, their plan would produce $2.2 trillion in budget savings over the coming decade: $800 billion in higher taxes, $600 billion in savings from costly health care programs like Medicare, $300 billion from other proposals such as forcing federal workers to contribute more toward their pensions and $300 billion in additional savings from the Pentagon budget and domestic programs funded by Congress each year. Boehner signaled in discussions with Obama in 2011 that he was willing to accept up to $800 billion in higher tax revenues, but his aides maintained that much of that money would have come from so-called dynamic scoring â¿¿ a conservative approach in which economic growth would have accounted for much of the revenue. Now, Boehner is willing to accept the estimates of official scorekeepers like the Congressional Budget Office, whose models reject dynamic scoring.
