At the same time, an estimated two million Americans have been dropped from their previous healthcare coverage, as their plans did not adhere to Obamacare's strict new coverage standards, and some analysts predicted the number could reach the tens of millions.
The development has put Obama in hot water, as he vowed numerous times in recent years that those who liked their insurance policies could keep them.
The Gallup poll found that Americans' most common complaint about the new law is a philosophical objection -- government interference or forcing people to get healthcare -- mentioned by 37 percent of those who disapprove.
Twenty-one percent believe the law will increase costs and make healthcare less affordable. Eight percent specifically mention planning, design, or website problems; another 8 percent say the law is "not working".
