Does this refer to US liberals mainly? I ask because the liberal party of Australia is closer to the Republican party of the US. I am not very "up with the play" when it comes to US politics. [[User:MaxFletcher|MaxFletcher]] 15:45, 21 March 2011 (EDT)
:Yes, it refers to US liberals mainly (who generally belong to the Democratic Party). More generally it refers to the philosophy or ideology of [[liberalism]]. See that article for what we mean by "liberalism".
