WYSK: There funded by dark money PACS, but some good reporting has brought out these names: David Koch, Peter Thiel, Reid Hoffman, Mark Cuban, Harlan Crow, and Michael Bloomberg. Some of there members are most famous for stopping big bills. Joe Leiberman, for example, single handedly stopped the single payer portion of the ACA. Senators Joe Manchin and Kyrsen Simena kept the John Lewis voting rights act from passing, and famously kept the senate from repealing the filibuster.
We do a lot of weird word play in the US. Liberal, for example, has come to mean something akin to left wing. In the rest of the world liberal would idealogically be a much closer fit with something like a center right party. Or it would have elements of both (personal freedoms combined with limited government).
