Will the fiscal cliff vote cost John Boehner his speakership?

In the eleventh-hour effort to avert the so-called "fiscal cliff," House speaker John Boehner (R-Ohio) angered many of his fellow Republicans not only by voting for the $4 trillion package needed to extend tax breaks, increase taxes on the rich and trim some spending, but he did it in a way that sidestepped major spending cuts proposed by the likes of Majority Leader Eric Cantor (R-Va.), who both led GOP opposition to the package and is poised to replace Boehner.
