"""Supply-side voodoo — which claims that tax cuts pay for themselves and/or that any rise in taxes would lead to economic collapse — has been a powerful force within the G.O.P. ever since Ronald Reagan embraced the concept of the Laffer curve. But the voodoo used to be contained. Reagan himself enacted significant tax increases, offsetting to a considerable extent his initial cuts.
And even the administration of former President George W. Bush refrained from making extravagant claims about tax-cut magic, at least in part for fear that making such claims would raise questions about the administration’s seriousness.
Recently, however, all restraint has vanished — indeed, it has been driven out of the party. Last year Mitch McConnell, the Senate minority leader, asserted that the Bush tax cuts actually increased revenue — a claim completely at odds with the evidence — and also declared that this was “the view of virtually every Republican on that subject.” And it’s true: even Mr. Romney, widely regarded as the most sensible of the contenders for the 2012 presidential nomination, has endorsed the view that tax cuts can actually reduce the deficit.
Which brings me to the culpability of those who are only now facing up to the G.O.P.’s craziness.
Here’s the point: those within the G.O.P. who had misgivings about the embrace of tax-cut fanaticism might have made a stronger stand if there had been any indication that such fanaticism came with a price, if outsiders had been willing to condemn those who took irresponsible positions." """
Krugonomics is not really Contingencies' cup of tea but PK does point out one fairly obvious fact: the Republicans will make shit up when necessary, and the Herd will generally buy it (as with the Laffer curve BS, one of the greatest prevarications of the last few decades)
