Apparently scrambling for votes on their alternative to a fiscal cliff deal – known as Plan B – House Republicans late Wednesday were considering expanding the scope of their tax cut extension measure to include spending cuts.

The measure, according to GOP sources, would be modified in an effort to win support from Republicans who were concerned the extension without spending cuts was a net tax increase. Plan B was initially advanced by House Speaker John Boehner as a method to ensure the GOP is not connected with a middle class tax increase if a fiscal cliff deal is not reached.

One of the sources said the concept is helping with some members, but not others.
