> or even win re-election

I mean, I would like to know what percentage of people makes an informed decision when voting for a judge for example.

A lot of them run unopposed anyway. And if they don't, I have no idea how you would figure out what candidate you like best.

Heck, in the US even the big political positions seem to be largely void of 'ideas'. It's mostly attack ads paid for by shady sources through PACs. That's where the majority of the votes are flipped/won...
