The state I lived in previously recently approved and instituted a state "education" lottery, where all the proceeds would benefit the education system. The campaign was relentless for a few years until approved.

What they _didn't_ tell people was that, upon approval, most state funding would stop and be _replaced_ by the lottery proceeds.

In the end it turns out that the lottery proceeds were much less compared to the state funding and, therefore, the educational funding has been greatly reduced.
