I'm familiar with Virginia (lots of friends down there) - UVA and W&M get 10%, JMU gets >25%, VT is around 20%. not sure about the other state schools like ODU and VCU.
The flagship schools are getting squeezed hard because of the perception of having enough endowment and donors to cover some of the gap. Instead, I am getting almost daily emails and monthly flyers soliciting donations because my school is claiming poverty.
Yeah, not sure what it is on the aggregate for VA public colleges but definitely the folks in Charlottesville have complained about cuts for years now. CWM too, I suppose...taking your word for it. Perhaps because both have smaller enrollments than VPISU so they've lost some leverage to their counterparts in Blacksburg over the years, though I would think both still have significant influence in Richmond.
