President Obama's trustworthiness has taken a serious hit during the first two months of the rollout of his health care law, according to a new poll by CNN/ORC International.

The poll released Monday morning shows that, for the first time, a majority of Americans at 53 percent believe the president is not honest and trustworthy.

The survey also showed a sharp decline in the number of people who say Obama can manage the government effectively – now at 40 percent, down from 12 percent in June and the worst score the president received in the survey, which tested how people view nine personal characteristics.

"A lot of attention has focused on the President's numbers on honesty in new polling the past three weeks, but it looks like the recent controversy over Obamacare has had a bigger impact on his status as an effective manager of the government, and that may be what is really driving the drop in Obama's approval rating this fall," CNN Polling Director Keating Holland said.

The numbers tick even higher – up to 53 percent disapproving – when Americans are asked if Obama is a person they admire. An equal number say they don't agree with him on important issues or view him as a decisive leader, and 56 percent say they don't believe he inspires confidence. All of these are record lows for Obama in CNN's polling.

One positive note in the poll: Most Americans still view him as someone who cares about ordinary people with six in 10 saying he has a vision for the country's future and seven in 10 saying he is likable.

The poll was conducted Nov. 18-20 for CNN by ORC International with 843 adults questioned by telephone.
