Drudge Retort (Retort, not serial liar Matt Drudge's smear site Report) reports that a Sachs/Mason-Dixon poll shows that 65% of Americans support a balanced budget amendment to the constitution. That summary page links to the Daily Caller, and I couldn't find any where other than the right-wing blogs that are reporting on this poll, so
here's the full poll in PDF format. The poll states: "81 percent of Republicans, 68 percent of independents, and 45 percent of Democrats support a balanced budget amendment to the U.S. Constitution," and "The amendment is opposed by 44 percent of Democrats, 11 percent of Republicans and 25 percent of independents surveyed." So among Democrats polled it's rather split: 45% support, 44% oppose, and 11% don't know.
This result came from the question "Currently, nearly every state in the nation has a balanced budget amendment, prohibiting states from spending more then they have. The U.S. Congress, however, is not currently required to balance the federal budget. Do you support or oppose an amendment to the U.S. Constitution requiring Congress to pass a balanced budget every year?"
Also, in response to the question "If a presidential candidate supported a balanced budget amendment, would you be more likely to vote for them, less likely to vote for them, or would it not have a major effect on your voting decision?" Among all voters 46% said "more likely" (including 51% of independents); among Democrats 21% said more likely, 37% less likely, 35% no effect, 7% not sure.
