Republicans rarely meet a tax cut that they don't like. Now that they have found one, they are finding it politically impossible to stop it.
On Tuesday, President Obama called on Congress to extend a 2 percentage point reduction in payroll taxes, which fund Social Security. The cut, enacted last year, is otherwise set to expire at the end of the month.
The current cut means a savings of about $20 a week to a worker who earns $50,000 a year and about $2,000 a year to someone making $100,000.
