Speaking on the Senate floor Tuesday, Minority Leader Mitch McConnell, R-Ky., downplayed a potential GOP mutiny over the payroll tax cut and urged Senate Democrats to let conferees negotiating the extension to finish their work.Last year, Democrats and Republican were engaged in a hot debate over extending a cut in Social Security payroll taxes for 160 million American workers. Both parties said they favored the middle-class tax cuts, but instead of a year-long deal lawmakers were only able to compromise on a short-term agreement that is set to expire February 29.McConnell says Republicans strongly support extending the holiday for the rest of the year, but the GOP rejects a tax hike on wealthier Americans as a way to pay for the relief."When a tax hike that’s been rejected repeatedly by members of both parties over the past year is the opening bid in a negotiation, I think it’s safe to say that Democrats are more interested in scoring political points than in scoring a tax cut that millions of middle-class Americans are counting on," he says. "When the Democratic Majority Leader (Harry Reid) of the Senate suddenly drops a proposal of his own to extend this tax cut even as a conference committee is in the midst of negotiating a bipartisan solution that everybody can support, I think it’s pretty obvious that the problem isn’t with Republicans." Last year, Republicans took a hit in the polls over the debate and reports of internal divisions amongst GOP lawmakers over what strategy to take this time are boiling over into the public.From Politico:
