From further up the thread

A liberal is someone who:

• Upholds the modern nation state and is thus against monarchy (against whom the first liberals rebelled against)
• Upholds capitalism and market economies, and with it property rights
• Upholds electoral parliamentary systems of governance
• Usually believes in some version of the social contract or similar theory from which the legitimacy of the nation state and capitalism is derived.

This describes the bulk of the Democrat and Republican parties. US politics doesn't have a left-wing as it is understood in the rest of the world, our center is between two right-wing ideologies.
