Congressional approval ratings took a 10-point hit this month, because fewer Democrats view Congress favorably, according to a new poll's findings.

Only about 21 percent of surveyed voters in Gallup's latest survey, released Tuesday, indicated they approved of the way Congress was handling its job, down from 31 percent just last month. At the same time, disapproval ratings have jumped about 9 points since September, from 63 percent to 72 percent, according to the poll.

But most unhappy in October seem to be registered Democrats. Only about 36 percent of the party's self-identified voters said in the poll they approved of Congress' work -- down 18 points since just last month. Of course, Republicans and Independents too have grown increasingly unhappy with the legislative branch -- approval among those groups dropped four and seven points, respectively -- but the decline of support among Democrats is nonetheless striking.
