The anti-Federalists were made up of anyone who was poor and not a big landowner, anyone tired of being controlled, anyone who wanted the people's votes to directly count and anyone who wanted to protect their rights. The anti-Federalists were made up of all different types of people, while the Federalists were mainly upper class. The anti-Federalists represented the United States population as a whole better than the Federalists.
When it came to the way the government was run the anti-Federalists wanted the complete opposite of the Federalists. The anti-Federalists wanted their power in the legislature, mainly the lower house where every state has one vote. They wanted the terms of office to be shorter, with limits on how many terms you could serve. These officials were not to be elected by representatives but directly by the people of the United States.
The only way the anti-Federalists would ever even consider helping to ratify the Constitution was if it contained a Bill of Rights, which they thought was "essential for preserving the individual liberties" (www.consitutioncenter.org) of the people. Without this document the government could control every one like a tyranny. To them the Constitution without the Bill of Rights was just a weapon of the upper class against the poor.
The figurehead of the anti-Federalists was Thomas Jefferson who later became President of The United States. The funny thing about Jefferson was for a long time he would not choose sides between the Federalists and the anti-Federalists, he was totally against political parties. He was for a strong central government, which was more of a Federalist's view.
