It’s from the West Wing, but the sentiment is correct
Santos: It’s true, Republicans have tried to turn ‘liberal’ into a bad word. Well, liberals ended slavery in this country.
Vinick: A Republican president ended slavery.
Santos: Yes, a liberal Republican. What
happened to them? They got run out of your party. What did liberals do that was so offensive to the Republican party? I’ll tell you what they did. Liberals got women the right to vote. Liberals got African-Americans the right to vote. Liberals created social security and lifted millions of elderly people out of poverty. Liberals ended segregation. Liberals passed the Civil Rights Act, the Voting Rights Act, Liberals created Medicare. Liberals passed the Clean Air Act, and the Clean Water Act. What did Conservatives do? They opposed every one of those programs. Every one. So when you try to hurl the word ‘liberal’ at my feet, as if it were dirty, something to run away from, something that I should be ashamed of, it won’t work, Senator, because I will pick up that label and wear it as a badge of honor.
