The Republican lawmaker defended his budget stance during a Saturday meeting with Cobb County Republicans.
Chambliss has been criticized by some Republicans for saying in a recent interview that he might break a public pledge not to raise taxes that he signed years ago with Grover Norquist's Americans For Tax Reform.
Chambliss said the country was not in such a dire financial predicament when he signed the pledge.
He said no one will dictate his votes.
Chambliss said he supports eliminating some tax deductions to raise government funding if it were accompanied by major spending cuts.
