SV Summary
Voters can record their first and second preference (more voter choice and reduces wasted votes) If no candidate wins majority after the first vote everyone but the top 2 are eliminated then the 2nd performance would continue to have an impact but being added to the top 2
IF U DONT WIN THE MAJORITY 1ST TIME THE WINNING CANDIDATE COULD GET A BOOST AND INCREASE THEIR MANDATE
