Voting should be allowed, but of course the jokehovians will think of anyone that gives in and votes under mandatory voting as "spiritually weak" or even as "brazen conduct" to avoid directly disfellowshipping anyone for voting. Every legal citizen should be allowed to cast one vote. I would view it as wrong to rig the election, say so communism and tyranny can rule--to the point where anyone pushing communism in this way is an enemy to the state and deserves the death penalty for high treason. (Especially at the levels that it has been happening in France, Italy, Germany, Canada, and the United Tyranny of Stupidity as of late.
But, making voting mandatory is just as bad. In light of what happened in the above countries where the majority of people voted for freedom only to have their votes thrown out and votes for tyranny fabricated, voting has become a useless exercise. Anyone opposing tyranny is seen as the enemy, and votes for freedom are drowned out or "lost". And this should not be seen as a chance for the washtowel to crack down on voting--itself a form of manipulating the election. Preventing legal citizens from voting prevents them from voting for freedom instead of tyranny.
