WASHINGTON -- US President Barack Obama's job approval rating dropped to its all-time low, while the opposition to his signature healthcare overhaul hit record high, according to a new Washington Post-ABC poll released on Tuesday.

The latest poll found that 42 percent of Americans approve of Obama's job performance, the lowest point during his presidency in Washington Post-ABC polls. The latest approval rating dropped 6 percentage points in a month.

According to the new poll, Obama's disapproval rating stands at 55 percent, and 44 percent of Americans say they strongly disapprove of his job performance, both the worst of his presidency.

The new poll also showed that for the first time in his presidency, a majority of Americans, 52 percent, hold an unfavorable view of him, while 46 percent of Americans view him favorably.

Opposition to the healthcare law hit a record high in the latest Washington Post-ABC poll, with 57 percent of Americans opposing the president's most significant domestic initiative, while 40 percent supporting it. The public was almost divided in its assessments of the law almost a month ago, when the centerpiece of the healthcare overhaul entered into its enrollment period.

Obama sought to rally supporters on Monday night to help with the enrollment of the error-ridden online insurance marketplace, a centerpiece of the healthcare overhaul aiming to get more uninsured Americans coverage.

The flawed website of the federal online market has undergone failures since its debut on October 1 and was almost out of service during the first two weeks of operation. Many consumers have reported difficulties of signing up and getting enrolled.

Federal officials announced last week that only about 106,000 people signed up for coverage in the online marketplace in its first month. The figure is well below the administration's expectations to enroll 500,000 people by the end of October.

The Obama administration has vowed to fix the broken website by the end of this month.
