15-1 To Vote or Not To Vote

Mr. and Mrs. Ward typically vote oppositely in elections and so their votes "cancel each other out." They each gain two units of utility from a vote for their position (and lose two units of utility from a vote against their position).

What is the equilibrium of this game? Discuss whether the entrant is better off with or without the ability to withdraw.
