共 - here meaning “together”, “joint” or “common”
和 - here meaning peace or harmony.
The connection here is a peace/harmony/order (because peace/harmony stems from order) that comes from “together” or “joint” (rule). Hence, republicanism (as in the ruling system).
It is the literal translation of the names of the parties.
Democracy party
Republicanism party
