Americans are split over the deal lawmakers struck this week to avert the "fiscal cliff," with 43 percent saying they approve and 45 percent saying they disapprove in a Gallup poll conducted Thursday.

The agreement, which raised taxes on wealthy Americans while preserving middle-class rates, was received considerably better by Democrats than Republicans, the poll shows. Sixty-seven percent of Democrats approve of the measure, while nearly as many Republicans — 65 percent — disapprove.
