A Liberal is someone who believes in liberalism, which is an ideological and political philosophy that supports freedoms and equality. These can include gender equality and free speech, among others.
A Democrat is a member of the Democratic Party, which is a left-leaning political party that believes in using government to promote social and economic justice. This includes a strong social safety net and progressive taxation, along with regulation to protect workers and the environment.
The Democratic Party, established around 1828, is one of the oldest and most prominent political parties in the world. It has a large number of members, including those from a variety of backgrounds and ethnicities.
It is divided into two main groups: Progressive Left and Establishment Liberals.
Those who identify with the Progressive Left are majority White, non-Hispanic Americans who have very liberal views on virtually every issue and support far-reaching changes to address racial injustice and expand the social safety net.
They also want to see significant change in the way government works, and believe that most laws and institutions need to be completely rebuilt.
Many of them also favor a flat tax (same tax rate for all income) and want to abolish the Environmental Protection Agency, which they feel hinders free market capitalism and job growth.
Some of them are moderates and want to continue working within the system to achieve a better society, while some of them want sweeping changes that will make all Americans feel equal. But the differences between these types of Democrats are wide and deep.
