Step-by-step explanation:
The Democratic Party has different factions, one of them is more progressive, and the other is more centrist, or liberal. In spite of this, the party as a whole agrees with the idea that the American healthcare system should be reformed.
Most of the democratic presidents in the 20th century have tried to reform healthcare by increasing government intervention. Franklin D. Roosevelt created Social Security, Medicare begun during the Lyndon B. Johnson administration, and Obama signed into law the Patient Protection and Affordable Care Act in 2010.
