Answer:
Libertarian Party.
Step-by-step explanation:
I'm going to give you an answer that you likely won't like, especially if you expect the answer to be either the Democrats or the Republicans.
Liberalism has two commonly used definitions.
1. The toleration of other opinions besides one's own. In the beginning, while the constitution was being written. There was a lot of screaming and banging of the order gavil, but that did not mean that there wasn't any respect. Opposing opinions were listened to. The founding fathers took each other's opinions very seriously: all of them were well aware that they were committing treason by considering the Declaration of Independence and the Constitution.
2. Liberalism is also a way of looking at money, at society. at individual rights, and at democracy.
Neither the dems or the republicans really take these two views very seriously. They are both more willing to deal with power.
The answer to your question is the Libertarian party. The Democrats used to be concerned about these two points. No longer.
