I don't know what a "level playing field" is. If that means all the candidates tell the truth, and the media reporting shows no favoritism, I think the ultimate result could be a confused public. Or, it could be an informed public that will choose based on something more than platitudes.
When one candidate has most of the money, establishment, and MSM behind him, the playing field isn’t level. This is what Sarah was referencing.
It would mean no clear winner and a brokered convention.
