What did Liberals do that was so offensive to the Republican (note, original quote says "liberal") 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, the Clean Water Act. What did conservatives do? They opposed them on every one of those things every one. So when you try to hurl that label at my feet, 'Liberal,' as if it were something to be ashamed of, something dirty, something to run away from, it won't work, Senator. Because I will pick up that label and I will wear it as a badge of honor."
Someone should tell Democrats that Susan B. Anthony voted straight ticket Republican, Martin Luther King Sr. was a lifelong Republican (at least until the 1960s when RFK acted on behalf of his son MLK Jr., but he might have thought differently if he knew that the Kennedys were also wiretapping MLK Jr.'s phone calls), Jackie Robbinson was a Republican...
The KKK was founded by Democrats. A greater percentage of Democrats voted against the Civil Rights act, blah blah blah.
Don't confuse a liberal with facts or history.
Hugh Hewitt’s book “If It’s Not Close They Can’t Cheat” includes as an epigram a paragraph from a speech by an Illinois Attorney General wherein he reminded his listeners that every hand that ripped Old Glory down before the Civil War was the hand of a Democrat, and every war wound the Union veterans in the room had was a “souveneir of a Democrat.”
