What has Barack Obama done that gets so many people angry?
Do you think Obama's healthcare plan is controversial?
Yes, the Affordable Care Act (ACA), also known as Obamacare, has been a polarizing issue since it was passed in 2010. Supporters argue that it has expanded access to healthcare for millions of Americans who previously lacked insurance, while critics contend that it has raised costs and resulted in long wait times for medical treatment.
