Prop. 106 on the Aug. 27 Phoenix ballot is the latest plan promising to deal with the city's $4 billion in unfunded pension debt. That's how much Phoenix will owe retirees in future years, but hasn't covered yet. 

Prop. 106 would pay down the public-safety portion of the debt much faster, by capping city spending on most services - almost everything except public safety.

The Arizona Republic's Jessica Boehm explains both sides of the issue, and why there are unintended consequences and unanswered questions.

A "yes" vote would approve the faster paydown of debt; a "no" vote would stick with the current plan for paying it down. 

More "Sunday Square Off":

- Arizona congresswoman claimed Mueller report was 'regurgitated.' So I read it back to her.

- Democrat Adrian Fontes was elected to run county elections. So why isn't he doing that anymore?

- Senate candidate Mark Kelly wants to be transparent. Is he going far enough?
