What states have it the best?
Florida, Ohio, Texas???
Ohio and Michigan are nice because they have a wide array of schools. Ohio has low-range (NEOMED, OUHCOM which is DO), mid-low range (Wright, Toledo), mid/upper-mid (Cincinnati, Ohio State) and high-end (Case). Lot of these schools (MSUCOM, Cincy) are very cheap for IS. Also, some east/west coasters don't want to live in the Midwest for various reasons, cutting down the pool. I'd say Tennessee (4 schools I think) and Kentucky (3 schools) also have it pretty good, for IS students anyway.
If you just want to get into med school, deep south is where it's at. Alabama, Louisiana, Mississippi all have big IS biases. UMiss has a mediam MCAT score of 28 and only accepts IS. Alabama and Louisiana each have 3 schools and not many applicants.
And how about U of North Dakota? 110 IS applicants, 106 IS interviews, 49 IS acceptances? Can't argue with that.
Texas and Florida don't have it good because, despite having lots of schools, they also have a TON of qualified IS applicants. Ohio and Michigan don't.
