Senate Republicans Tuesday may have blocked President Obama's jobs bill, but a new poll suggests that's not what a majority of Americans want.

Nearly two-thirds of the respondents to a survey from NBC/Wall Street Journal voiced their approval when pollsters were told them the details of the president's "American Jobs Act"-- including that it would cut payroll taxes, fund new road construction, and extend unemployment benefits. NBC reports that 63 percent of respondents said they favored the bill, with just 32 percent opposing it.

But the numbers for the bill only spike when Americans learn about its provisions in some detail. When NBC pollsters asked for a simple up-or-down appraisal of the bill, minus any policy details, the same group of respondents expressed less than half the level of support that they later showed. "When asked simply if Congress should pass the legislation or not, 30 percent of respondents answer yes, while 22 percent say no; 44 percent have no opinion," according to NBC.

One element of the bill in particular enjoyed wide support--Obama's proposal to remove tax loopholes for the wealthiest Americans. Sixty-four percent of respondents said it is a "good idea" to raise taxes on the wealthy and corporations. Thirty-one percent said it was a bad idea.

The poll, which has a margin of error of plus or minus 3.1 percentage points is set for release Wednesday at 6:30 p.m. ET.

On Tuesday evening, senate Republicans joined together to filibuster the president's jobs bill--denying efforts to begin formal debate on the legislation even though a majority of senators had already voted to advance the bill in a 50-49 vote.

The president first introduced the jobs bill in early September and has since been traveling across the country to make the case for his proposal.
