I wonder what he'd think of the Left and Democrats (which you IMO not entirely correctly called Social Liberals). This group unites the former post-reformed-communist party (SLD) he so despised, two of its former breakaways, and the social-liberal Democratic Party, the one party he liked.

Also, I'd term the League of Polish Families extreme-right.
