GOP Senate leader Mitch McConnell famously said a year ago that his main task in the 112th Congress was to make sure that President Obama would not be re-elected. Given how he and House Speaker John Boehner have handled the payroll tax debate, we wonder if they might end up re-electing the President before the 2012 campaign even begins in earnest.

The GOP leaders have somehow managed the remarkable feat of being blamed for opposing a one-year extension of a tax holiday that they are surely going to pass. This is no easy double play.

Republicans have also achieved the small miracle of letting Mr. Obama position himself as an election-year tax cutter, although he's spent most of his Presidency promoting tax increases and he would hit the economy with one of the largest tax increases ever in 2013. This should be impossible.

House Republicans yesterday voted down the Senate's two-month extension of the two-percentage-point payroll tax holiday to 4.2% from 6.2%. They say the short extension makes no economic sense, but then neither does a one-year extension. No employer is going to hire a worker based on such a small and temporary decrease in employment costs, as this year's tax holiday has demonstrated. The entire exercise is political, but Republicans have thoroughly botched the politics.

Their first mistake was adopting the President's language that he is proposing a tax cut rather than calling it a temporary tax holiday. People will understand the difference—and discount the benefit.
