We first have to see why. He likes Gtown for politics - so GW and AU would be natural backups. Even UMD. Au he can get into - because they live and die by demonstrated interest. A more likely target and very good politics school with good aid is U of Denver. GW - not as easy to get into and you really have to like the “urban-ness” - they don’t even have dining halls.
Again, nothing wrong with reach schools - and that’s UMich and UVA. Since he likes the location of Vandy and USC, I’ll assume he wants to be more in cities - so forgetting the weather - Miamii, Syracuse, U of Az (easy in and $$). I’m thinking Emory and WUSTL are out of reach - but you never know. Pitt would be another match - in city and great programs…maybe on a little smaller scale, Butler, an LA area schools such as Occidental or LMU (depending on religion), SMU - many are reaches though. Not sure Kelly fits - he’s not looking at business. I do think Denver would be a solid fit though - and maybe a school like U Cincy or even U KY.
Mid size schools in cities sounds like what he needs.
