Washington (CNN) -- They are losing the battle over higher taxes on the wealthy, so now Republicans are threatening a political war next year when it comes time to raise the nation's debt ceiling. With cracks appearing in their anti-tax facade and polls showing most Americans favoring President Barack Obama's stance in the fiscal cliff negotiations, GOP legislators are starting to advocate a tactical retreat to fight another day. Conservative Sen. Lindsey Graham, R-South Carolina, promised the newly re-elected Obama "one hell of a fight" next year if the president forces through his plan for high-income earners to pay more taxes without agreeing to substantive steps to reduce the nation's chronic federal deficits and debt.

Boehner's side wants additional revenue to come from tax reform, such as eliminating some deductions and loopholes, while @placeholder demands the higher rates on income over $250,000 for families as part of the equation.
