If insanity is doing the same thing repeatedly and expecting a different result, then continuing negotiations on a deal to avoid the fiscal cliff might amount to little more than crazy talk.
The same players are arguing about the same issue -- taxes -- in a repeat of budget showdowns of the past two years that failed to reach a comprehensive agreement.
President Barack Obama's re-election in November, coupled with a perceived desire by congressional leaders to shed their reputation of dysfunction, raised expectations for a possible deal.
However, with four weeks to go until the automatic tax hikes and spending cuts of the fiscal cliff get triggered, the two sides remain unable to resolve a central issue -- whether wealthy Americans should pay more taxes than they do now.
Fred Smith, the chief executive officer of FedEx Corp., considered a bellwether on the economy, told CNN Tuesday that he and other top business leaders "look at the situation in Washington with complete amazement and dismay."
"The problem is the ideological pinnings on both sides of this argument are so difficult to bridge," Smith said, adding it will "be hard for them to get a deal."
Polls show that more Americans will blame Republicans, instead of Obama and Democrats, if there is no deal and the nation goes over the fiscal cliff.
A Washington Post/Pew Research Center survey released Tuesday put the margin at 53%-27% in citing Republicans or Obama. A CNN/ORC International poll released last week showed 45% would blame congressional Republicans compared to 34% who would blame Obama.
All signs point to a continuing standoff, at least for now. No formal negotiating sessions are known to be scheduled and congressional aides said Tuesday no back-channel discussions were taking place.
Obama and House Speaker John Boehner did not speak or get photographed together at Monday night's White House holiday reception for members of Congress, though one GOP source cautioned against reading anything political into the lack of interaction at a social event.
At issue are competing proposals by Obama and House Republicans that coincide in some areas but differ on the tax-rate question.
Obama demands the House immediately pass a measure already approved by the Senate to extend tax cuts for families making less than $250,000 a year while allowing rates to return to higher Clinton-era levels for wealthier households.
Both sides agree that the 98% of Americans making less than $250,000 a year should avoid a tax hike when the tax cuts from the Bush administration expire on December 31, Obama and Democrats argue. They call for the House to guarantee that outcome by passing the Senate measure now.
Once that happens, Obama and Democratic leaders promise, they will work out compromises on other deficit reduction steps sought by Republicans, such as reforms to the Medicare and Medicaid entitlement programs as part of further spending cuts.
In an interview with Bloomberg TV broadcast Tuesday, Obama said Republicans need to accept the reality that deficit reduction requires higher tax rates on the wealthy.
"The issue right now, that is relevant, is the acknowledgment that if we're going to raise revenues that are sufficient to balance with the very tough cuts that we have already made and the future reforms in entitlements that I'm prepared to make, then we are going to have to see the rates on the top 2% go up, " the president said. "We will not be able to get a deal without it."
House Republicans led by Boehner made a major counter-proposal Monday, offering a series of steps to reduce the nation's chronic federal deficits by $2.2 trillion over 10 years.
The GOP leaders gave ground by calling for $800 billion in deficit reduction through tax reform, including an unspecified amount from eliminating some deductions and loopholes.
At the same time, they rejected the Democratic call for higher tax rates on wealthier Americans, contending the move would inhibit economic growth by raising taxes on small business owners, many of whom declare business profits on their personal income tax returns.
On Tuesday, leading conservatives blasted the House Republican proposal that breaks with years of GOP orthodoxy by calling for more taxes to be paid by wealthier Americans.
But in a sign of how politically treacherous and awkward the offer has become, top Senate Republicans -- many of them conservatives -- withheld harsh criticism of the plan even as they refused to embrace it. In fact, despite their general misgivings about approving tax increases, they gently nudged negotiations forward, in apparent recognition that any final agreement would include higher taxes -- at least in some form -- as Obama demands.
Sen. Jim DeMint, R-South Carolina, said the "offer of an $800 billion tax hike will destroy jobs and allow politicians in Washington to spend even more." Sen. Rand Paul, R-Kentucky, said it would be "a huge mistake to raise taxes. It will cripple the economy."
Senate Republican Leader Mitch McConnell, meanwhile, sidestepped the question when at a press conference he was asked directly if he backed the plan.
"I commend the House Republican leadership for trying to move the process along and getting to a point where, hopefully, we can have a real discussion," he said.
Charles Grassley of Iowa, a senior Republican on the Finance Committee, was one of a only a few GOP senators who said he would support Boehner's plan to raise revenue, but only if there is a "willingness on the part of Democrats to accept spending cuts that are three to one or four to one."
