Make it more accessible and provide better candidates.

Accessible things like:

• nearly anything other than first past the post
• Mandated Paid time off to vote.
• Vote by mail(universal absentee ballot).
• Strict adherence to vote outcomes (Congress cannot ignore at state nor national level).
• full-stop limits on campaign spending
• reform campaign donation regulation
• limit campaign advertising to small window near election (e.g. 3 months prior)

Better candidates like:

• Anyone left of “defacing property is equivalent to or worse than assault on a person”
• One that has a platform people are excited to vote for

I promise you there’s plenty of highly educated idiots, such a test would only limit the voting base to elite idiots.
