I thought your question was a joke. I was waiting for a punchline like "Whichever admissions director you sleep with!"
In all seriousness, I don't think ANY medical school (MD or DO) is easy to get into. Sure, you can argue about the island schools where requirement for some of them are a pulse and a checkbook.
But, each school has its own set of numbers. The more intelligent premeds will tell you that "Average" numbers posted by a school mean squat. You need to have a competitive application all around.
Technically, the easiest DO school to get into would be the one with the smallest applicant:acceptance ratio. Who knows that? Who even cares?
Apply to a school because you want to go there, not because you can get in.
Good luck
