Is it effective to have my opponent arrested?
Solution 1:
Actually, it's the opposite of what you're thinking. If you arrest an opponent either before or in the elections, someone else would take his place with increased support, and the same ideals. As well, everyone who watched the arrest, and his/hers family will have decreased respect for you, meaning it will be more likely for them to vote against you. So it's not really beneficial to arrest anyone who's willing to go against you in the elections.
