Not by a substantial amount, but it’s not moving in the pro-stimulus direction for a vote that may take until next month to even come up in the U.S. Senate.

Public support for the economic recovery plan crafted by President Obama and congressional Democrats has slipped a bit over the past week. At the same time, expectations that the plan will quickly become law have increased.

Forty-two percent (42%) of the nation’s likely voters now support the president’s plan, roughly one-third of which is tax cuts with the rest new government spending. The latest Rasmussen Reports national telephone survey shows that 39% are opposed to it and 19% are undecided. Liberal voters overwhelmingly support the plan while conservatives are strongly opposed.

Last week, support for the President’s plan was at 45% and opposition at 34%.

As they consider the size and scope of the $800-billion-plus economic recovery plan, 46% are worried that the government will end up doing too much while 42% worry that it will do too little (see trends).

A plurality of men oppose the bill, while a plurality of women support it. Those making less than $40,000 per year are more likely to support the plan than those with higher incomes. Just 18% of Republicans support the Pelosi-Reid-Obama Debt Act of 2009, while 74% of Democrats do.

Perhaps the biggest surprise, however, is where unaffiliated voters stand. Last week found them split about evenly on whether the package should pass. Now, only 27% say it should, while a full 50% oppose it.

So basically this is a measure supported by a majority of Democrats and…few others. A majority of both Republicans and unaffiliated voters oppose the Debt Act.
