Given the election below:
Determine the winner (if there is one) using the methods:
a. Plurality
b. Condorcet
(As part of your solution draw a digraph which shows who beats whom. Use a directed edge from X to Y if X beats Y in a two-way contest.)
c. Borda count
(as part of your solution construct a pairwise preference matrix.)
d. Sequential run-off
e (Standard) Run-off
---------------------------------------------
f. Borda count sequential run-off
g. Coombs
h. Bucklin
Bucklin works as follow: If no one wins a majority based on the first place votes, look at only first and second place votes, to see if someone now has a majority. Continue until a winner emerges.
