Yet another new poll, this one by the NYT/CBS News, shows opinion on President Obama’s key policy priorities deteriorating, and his overall approval and disapproval numbers converging south of 50 percent.

Just 46 percent of those surveyed approve of the president’s job, while 45 percent disapprove. In December, the president’s split was 50/39.

Obama reached new lows in ratings of his job performance on health care (35/55), foreign policy (47/34), the economy (42/52), and his lowest approval rating, the federal deficit (31/58). Obama continues to poll relatively well on his handling of terrorism, but saw his numbers drop slightly to 55/34.

Health care ranked fourth as an overall concern for respondents, finishing behind “other.” And a majority of those polled (56/34) said they preferred “a smaller government providing fewer services” to a larger one.

Perhaps most strikingly, only 41 percent are “optimistic” that the stimulus bill will create jobs, and only and additional six percent of respondents believe it already has, while 48 percent believe that it will not.

UPDATE: Politico points to another remarkable element on the polling results: a mere eight percent of respondents would re-elect Congress. 81 percent say it is time for new representation.
