Yes! We do!

1) Take the general population. Some people say we should get rid of voting because people are too stupid. They are wrong. Our enemies have poisoned our nation to make us stupid so there would be an excuse to get rid of voting. We need to turn this on its head. We can use it to blackmail them. Just think, those stupid people might vote for ANYONE or ANYTHING. Bwahahaha Comacho for president!

2) On an individual basis, if you give someone the right to exclude people from voting for being stupid then all they have to do is use neurotoxins on all the people that have opposing political views and BOOM! Those views are no longer represented. DO YOU WANT TO GIVE YOUR ENEMIES MOTIVATION TO MAKE YOU STUPID?

Idiots voting is a GOOD thing.

If you want to stop it, improve education, healthcare, and defense so the idiots get smart. But you have to IMPROVE IT, not just throw money at it.
