Alan Simpson and Erskine Bowles, the co-chairmen of President Obama's bipartisan deficit reduction panel, earned the good regard of centrist pundits in Washington, D.C., for proposing a fairly balanced plan in 2011 that included both new tax revenues and spending cuts. But a balanced plan was not to be: Obama's negotiations that year with House Speaker John Boehner (R-Ohio) to reach a grand bargain foundered on their inability to reach a compromise. Still, the Simpson-Bowles plan endured as a rare beacon of common sense shining through the partisan miasma in Congress, and the two men have come to be seen as authorities on budget matters. As Steve Benen at The Maddow Blog explains:

[T]he original goal of Simpson and Bowles was to spread the pain around, creating a plan that neither side would love, but which would tried to make everyone feel the pinch in roughly the same quantities. Democrats and Republicans would complain, but they could stomach the package, the argument went, knowing that their rivals were sacrificing just about as much as they were. [MSNBC]

Now, Simpson and Bowles have returned with a new plan, on the eve of $1.2 trillion in scheduled spending cuts — known as the sequester — that will hit the Defense Department and discretionary spending programs. President Obama has called on Congress to pass a stopgap measure of modest spending cuts and new revenue, while Republicans have demanded that Obama replace the sequester solely with spending cuts to both discretionary and entitlement programs. Some have already hailed the return of Simpson and Bowles as a badly needed voice of sanity in the budget debate. The editorial board at USA Today says:

Please, would someone give Alan Simpson and Erskine Bowles an award already!...

The latest plan from Simpson, a former Republican senator from Wyoming, and Bowles, who served as President Clinton's chief of staff, usefully rattles the cages of both parties. Beyond the $2.6 trillion in deficit reduction already enacted, it calls for an additional $1.8 trillion in spending cuts, something Democrats resist, and $600 billion in tax revenue, something Republicans hate. [USA Today]

Liberal commentators, however, have pointed out that the original Simpson-Bowles plan had $1.50 in spending cuts for every $1 of revenues, while its sequel has a $3 to $1 ratio in favor of spending cuts. What happened?

Simpson and Bowles decided to use as their starting points the final offers that Obama and Boehner made to each other during the fiscal cliff talks at the end of 2012. In those negotiations, Obama asked for fewer revenues than what Simpson and Bowles had originally proposed. On the other side, Boehner asked for far more spending cuts than in the Simpson-Bowles plan. In essence, the latest plan from the venerable statesmen occupies the midpoint of what Obama and Boehner had offered, skewing the plan heavily toward spending cuts.

This is the problem of Washington's obsession with centrism, says Greg Sargent at The Washington Post:

[The plan] provides a useful window into the arbitrariness of Beltway conceptions of what constitutes the ideological "center." After all, the Boehner fiscal cliff plan raised taxes only on income over $1 million; the Obama offer raised taxes only on income over $400,000. Both of these are to the right of the balance Obama just won an election on: The expiration of the Bush tax cuts for income over $250,000. Yet these were designated the two ideological outer poles for the purposes of defining the debate. [The Washington Post]

The new plan also shows the extent to which Republican opposition to tax increases has shifted the goalposts, says Jonathan Chait at New York:

If the new Bowles-Simpson plan has any value, it is as a marker in the sheer power of Republican obstinacy. After all, since the first Bowles-Simpson plan came out, President Obama campaigned centrally on raising taxes on the rich as part of a debt-reduction plan and won a surprisingly comfortable re-election. And yet the center of the budget debate has moved sharply rightward. The distance between the first and second versions of Bowles-Simpson are an almost mathematical tabulation of the unequal interest the two parties have in compromising. [New York]

But while liberals may be disgruntled, Simpson-Bowles 2.0 may end up being killed by the side that would benefit the most from touting a supposedly bipartisan plan. Republicans, after all, have vowed not to raise any new revenue — which means the new plan is a non-starter for both parties.
