In most of the world, "liberal" doesn't mean the left half of the political spectrum. In many places it's the centerish part and in a few places it's the rightish part. In the US, until recently, almost all mainstream politicians were liberal in this sense (even while many of the Republican liberals used "liberal" as an epithet in campaign ads).

> Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, the right to private property, and equality before the law.[1][2] Liberals espouse various and sometimes conflicting views depending on their understanding of these principles but generally support private property, market economies, individual rights (including civil rights and human rights), liberal democracy, secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion.[3] Liberalism is frequently cited as the dominant ideology of modern history
