Confidence in the $787-billion economic stimulus plan has fallen four points in the week since President Obama signed it into law, and more voters are prepared to punish their representatives for supporting it.

Thirty-four percent (34%) of U.S. voters now say the plan will help the economy, while 32% believe it will hurt, according to a new Rasmussen Reports national telephone survey.

Twenty-six percent (26%) say the plan will have little impact on the economy. Eight percent (8%) are undecided.

A week ago, 38% of voters said the plan will help the economy, while 29% said it will hurt.

Investors are now evenly divided on whether the plan will help or hurt the economy. A week earlier they, too, were slightly more confident. Investor confidence has hit record lows for two days in a row in the Rasmussen Investor Index.

Fifty-nine percent (59%) of Democrats say the plan will help the economy, but 55% of Republicans think it will have a negative impact. Twenty-two percent (22%) of unaffiliated voters say it will help, 33% say it will hurt, and 31% believe it will have no impact.

These numbers mark a seven-point decrease in confidence among Democrats, and similar increases in concern among Republicans and unaffiliateds.

President Obama continues to enjoy solid job approval ratings and will be giving a nationally televised address tonight to build support for his first budget plan. During the debate over the stimulus package, a nationally televised press conference boosted support for that plan.

Half of all voters (51%) continue to believe it is at least somewhat likely that the stimulus plan passed by Congress will make things worse instead of better. That figure includes 32% who say it’s Very Likely to hurt.

Thirty percent (38%) now say the plan is unlikely to make economic conditions worse, with nine percent (9%) who say it is not at all likely. Twelve percent (12%) aren’t sure.

Forty-one percent (41%) of voters say they are less likely to vote for their representative in Congress if he or she voted for the stimulus measure, compared to 35% a week ago.

Twenty-nine percent (29%) say they are more likely to vote for a representative who supported the plan, a drop of three points in a week.

Sixty-seven percent (67%) of Republicans say they are less likely to vote for their representative if he or she supported the stimulus plan, while 11% say they are more likely to and 19% say it will have no impact on their vote.

Among Democrats, however, 48% are more likely to vote for a representative who supported the stimulus plan, with 19% who say they are less likely to do so. For 31%, it has no impact on their voting plans.

Forty-seven percent (47%) of voters not affiliated with either party are less likely to support a legislator who voted for the stimulus plan. Twenty-one percent (21%) are more likely, and 30% say there’s no impact on their vote.

Keep in mind that 67% of U.S. voters have more confidence in their own economic judgment than they do in that of the average member of Congress.

The stimulus plan passed the House and Senate with only three Republican votes.

But even before the vote, 60% of voters said the stimulus is mostly what Democrats want rather than a truly bipartisan product.
