There are two people running:

John Choi
Luke Kyper Bellville

This is a straightforward one. I like John Choi for a number of reasons, but the #1 reason for my respect for him is that he opted to prosecute the police officer who shot Philando Castile. Unsuccessfully: Yanez was acquitted. But you can’t guarantee outcomes as a prosecutor. You file charges, go to trial, and do your best, and he did.

Luke Kyper Bellville ran for judge in Hennepin County in 2016. Here’s what I wrote about him two years ago. He was clearly a flake candidate two years ago. Then he ran for Saint Paul school board last year; he was clearly a flake last year. He remains a flake. Basically the only content on his website are his answers to the questions from an ACLU questionnaire, which he seems to have scanned in; they’re fine. But he tells you nothing about his experience and qualifications, even to the point of reassuring voters that he has a law degree. (He does. I dug that up when he ran for judge two years ago.)

The pictures on his current website seemed so oddly chosen I ran a google image search and found a nearly-identical-in-design unfinished site on the same host. (Content warning: allegedly it’s a “before and after” site for a penis pump. When I visited on 9/30/2018, however, the pictures were the same as the ones on Bellville’s campaign site.)

Anyway: definitely vote for John Choi.
