Modern liberalism in America is simply not true liberalism. it is actually closer to statism. Statism is the idea that the state should control and regulate aspects of life. Liberalism, in its originally intended form, as described by Henry Thoreau, is exactly the same as modern conservatism. Conservatism in the United States is the conservation of the Founding Father's liberalism, classical liberalism. modern liberalism is simply statism and socialism.
"...liberalism is a misnomer for the liberals. If we were back in the days of the Revolution, so-called conservatives today would be the Liberals and the liberals would be the Tories." -Ronald Reagan
