The bill is not bad for Repubs - why would you want to repeal it ? It wouldn’t affect your taxes anyway unless you make more the $400K.
The payroll tax break was going to expire - I don’t believe it was part of the Bush tax cuts.
Obama got that temporary 1 year FICA/SS/payroll tax cut Dec 2010 as part of the 2 year Bush tax cut extension and then a year ago Dec 2011 O beat House Rs into submission extending it for one more year till now,
having been re-elected O doesnt need it anymore and the libs dont want it, so it just goes away.
