It never had a majority of support in the first place, but at least at first, the stimulus bill had a plurality in favor.  No longer.  Rasmussen’s polling shows that in two weeks, the numbers have flipped from 45-34 in support to 43-37 opposed:

Support for the economic recovery plan working its way through Congress has fallen again this week. For the first time, a plurality of voters nationwide oppose the $800-billion-plus plan.

The latest Rasmussen Reports national telephone survey found that 37% favor the legislation, 43% are opposed, and 20% are not sure.

Two weeks ago, 45% supported the plan. Last week, 42% supported it.

Opposition has grown from 34% two weeks ago to 39% last week and 43% today.

Barack Obama has lost seventeen points on the gap between support and opposition in just two weeks.  He’s lost ten points of support among Democrats, who now back it 64-16.  Unaffiliated voters oppose it even more than the general population, 50-27.  Only those making under $20,000 a year support the bill at all; all other income demographics have pluralities in opposition.

Not surprisingly, government employees also support it, 44-28.  The self-employed and private-sector employees both oppose it, the latter by a firm majority, 55-34.

What can Obama do to turn this around?  According to the poll, he could offer a tax-cut-only package, which has a plurality of support at 45-34.  A government-spending-only package would be opposed by almost three-quarters of all voters, 72-15.  Republicans have repeatedly offered a tax-cut stimulus plan, and they could benefit by getting the message out now about their alternative.

Clearly, though, Obama and the Democrats have begun to lose the confidence of American voters on their economic agenda.
