Pro successfully established that language is the most major factor in the creation of complex society, and thus under their framework making it the root. Throughout the debate the negative never squarely addresses the arguments made. Pro is also greatly helped by the superior structure and framing of their case. Pro wins!

Pro's framework of democratic legitimacy is accepted by Con, making this debate a question of whether mandatory voting leads to a more widely representative and respected government, as was also established by pro in the first round and not in any way disputed by Con until the last argument of the debate. For this reason framework falls entirely to the affirmative, giving Pro a lot of ground in this debate.

Pro provides a clean case that firmly upholds his framework. More turnout means more citizens are represented, which directly contributes to democratic legitimacy.

Con's case relates back to the framework far more weakly. He first of all make an argument that mandatory voting doesn't increase accurate representation because voters are being forced to choose between two options they dislike, but this simply isn't true. Pro made it abundantly clear that voters can cast protest ballots, which in its own way provides those citizens with a voice.

Con also argues that mandatory voting only leads to less educated voters, however they did not prove that someone voting without fully educating themself on the issues is destructive to democratic legitimacy. As Pro pointed, out every voter shows up to the booth with some knowledge of politics, and they know how their lives are going. Increasing turnout among voters who don't spend hours researching candidates still increases representation and thus in my view increasing democratic legitimacy.

Pro wins this debate!

Pro establishes a teleological framework, and this framework is not disputed by Con.

Pro's arguments sufficiently uphold their teleological framework, and neither the arguments made nor the framework itself was brought into question by Con. Thus, pro wins this debate.

Con effectively drops the entirety of the debate in the last round, solidifying Pro's victory, regardless of the framework used.
