Like Civic Platform, but unlike the fringe parties to the right, Law and Justice originated from the secular, anti-communist Solidarity trade union (which is a major cleavage in Polish politics) [REF].
Based on this voter profile, Law and Justice form the core of the conservative post-Solidarity bloc, along with the League of Polish Families and Solidarity Electoral Action, as opposed to liberal conservative post-Solidarity bloc of Civic Platform [REF].
