AIUI Dan Lipinski, formerly one of the House Democratic Caucus's
sh**ttiest most conservative members, would find himself at home in the German Christian Democratic Union. Lipinski self-advertises
as the Pope Leo XIII Fellow on Social Thought at the University of Dallas, expressing a strong affiliation for
the type of Catholic social teaching common among Christian Democrats. That said it's worth noting Lipinski himself
wavers on still identifying as a Democrat given his obvious squabbles ref. the party's liberalization and secularization.
