America's Third Largest Party The Libertarian Party is America's third largest and fastest growing political party. Libertarians engage in a variety of projects, working for everyone's liberty on every issue. The Libertarian Party was created in December of 1971 by people who realized that the politicians had strayed from America's original libertarian foundation, with disastrous results. Their vision was the same as that of America's founders -- a world where individuals are free to follow their own dreams in their own ways, a world of peace, harmony, opportunity, and abundance. The Libertarian Party of Florida in its current form was established in 1987.
