I am proud to be a liberal.

If by a "Liberal" they mean someone who looks ahead and not behind, someone who welcomes new ideas without rigid reactions, someone who cares about the welfare of the people — their health, their housing, their schools, their jobs, their civil rights, and their civil liberties — someone who believes we can break through the stalemate and suspicions that grip us in our policies abroad, if that is what they mean by a "Liberal," then I'm proud to say I'm a "Liberal."¹

President John F. Kennedy, Democrat, 35th President, 1917-1963
