This is an interactive tool to simulate the 2025 Irish Presidential Election using the Single Transferable Vote (STV) system. Adjust first preference votes and see how transfer preferences determine the final winner.
The Single Transferable Vote is a voting system where voters rank candidates in order of preference. If a voter's first choice is eliminated, their vote is transferred to their next preference. A candidate needs to reach a certain quota of votes (50% + 1) to be elected.
