The latest Rasmussen polls are sustaining a point I made a while back--Obama is losing 2 points a month, which puts in below forty before the summertime.

An approval rating in the thirties effectively means that you're toast.

Overall, 43% of voters say they at least somewhat approve of the President's performance. That, too matches the lowest level yet recorded for this President. Fifty-six percent (56%) disapprove.

Nearly 60% believe that Obama's health-care legislation will hurt the economy. Only 22%--basically your hard-core socialists, strongly approve of the President's performance. 43% strongly disapprove, which is well beyond wing-nut territory on the right. Most telling are the independents, who strongly disapprove at the rate of 45%. Only 17% of independents strongly approve.

By August, I think you'll start seeing stories about various Democrats mulling over the possibility of challenging Obama in the primaries.

UPDATE: Mark's comment mentions an unequivocal reality about these polls--blacks overwhelming approve of Obama.

95 percent of black voters approved in April, with just 3 percentage points fewer — 92 percent — approving of his current performance.

Yet its not fair to dismiss this as a black racism. As Frank Luntz points out:

"I think it makes perfect sense. ... African-Americans are more likely to support government intervention, they are more likely to support an activist government policy, they are less likely to trust corporations," he says. "And it also makes sense that the white communities become much more polarized [by the president's policies]; what doesn't make sense is that it has happened so quickly and so deeply."

I'll just note that black support for Boston Brahmin John Kerry--just about the whitest man I ever saw, was just a few points shy of where Obama is today. What it really comes down to is that the Democrat's socialist base is roughly fifty percent African American.
