crossvotes
A crossvote refers to a situation in a voting system where a voter casts a ballot for candidates from different political parties within a single election. This can occur in various electoral systems, and its prevalence and impact depend heavily on the specific rules of the election. For instance, in a two-round system, a voter might support a candidate from one party in the first round and then switch their allegiance to a candidate from a different party in the second round, if their initial choice is eliminated.
The phenomenon of crossvoting is often observed in systems where voters have the flexibility to choose candidates
However, crossvoting can also present challenges for political parties in terms of predicting election outcomes and
