Demand vs. supply

Today Jay Carney, Obama's press spokesman, asked "whatever happened to Republicans being for tax cuts"? He was referring to the Republicans attaching the Keystone Pipeline to the bill to extend the payroll tax cuts. Obama demanded there be no attachments. Most Republicans and some Democrats in Congress are supply-siders. They want to increase taxes or tax revenue not by cutting taxes, but by cutting marginal tax rates. Mr. Carney knows the difference. Payroll tax cuts (Keynesian) may give the economy a temporary boost, but it will be just that, temporary.
