Confidence in the $787-billion economic stimulus plan proposed by President Obama and passed by Congress in February continues to fall.

A new Rasmussen Reports national telephone survey finds that only 25% of U.S. voters now say the stimulus plan has helped the economy. That’s a six-point drop from a month ago.

Thirty-one percent (31%) say the stimulus actually hurt the economy, little changed from a month ago. However, this is the first poll showing that more voters believe the plan hurt rather than helped.

A plurality (36%) says the plan has had no impact.

Just after Congress passed the plan, 34% said it would help the economy, 32% that it would hurt and 26% predicted no impact.

Fifty percent (50%) of Republicans believe the stimulus plan has been bad for the economy. A plurality of Democrats (41%) disagree and say it has helped.

Voters not affiliated with either major party are more divided, but show less confidence in the plan than they did a month ago.

Criticism of the stimulus plan, intended in part to stem increasing unemployment, has grown with the recent release of a government report showing the unemployment rate at 9.5%, the highest rate since 1983. Government officials are predicting it will go higher, prompting talk of a second stimulus plan.

But 60% of voters oppose the passage of a second economic stimulus plan this year, while 27% think it’s a good idea.

Forty-five percent (45%) of Americans say the rest of the new government spending authorized in the first stimulus plan should now be canceled. Thirty-six percent (36%) disagree, and 20% are not sure.

However, while voters are opposed to another spending stimulus plan, 51% favor an across-the-board tax cut for all Americans.

The administration’s biggest current economic initiative, a retooling of the U.S. health care system, is now drawing increasing criticism as well. Fifty-three percent (53%) of voters oppose the health care reform plan proposed by the president and congressional Democrats.

Just 20% now say health care reform is the most important of the four budget priorities Obama laid out early in his presidency. Nearly twice as many (37%) say deficit reduction is the number one priority.

Fifty-one percent (51%) of voters worry that the government will try to do too much to fix the country’s economic problems, while 36% fear it won’t do enough. Seventy-six percent (76%) of Americans say it is at least somewhat likely that a large amount of money in the stimulus plan will be wasted due to inadequate government oversight.
