You have the left with "socialism" (even though the one state where they lead , they did just social democracy stuff) then greens doing greens stuff which is a big thing right now because the current government doesnt do Shit, then SPD who are supposed to do social democracy stuff but are definitly not doing anything in the government but doing what CDU wants, CDU , who are doing the stuff from social democracy to very conservative depending on who of the party has power and then you have the AfD who Just does right wing populism and tries to spread fear (which they are doing pretty Well it seems Like If you Look at the Recent right wing Attacks and their Poll numbers) to Interrupt the work of the parliamants (never ever will I vote for this piece of garbage Party that brought nothing but hate)
Then there is also the FDP, which are Like your average full on capitalism party.
Like These are the relevant ones.
So you have Like 3 left oriented and 3 right-oriented parties.
Depending on the state or City there can be also other relevant Parties.
