For Poli sci and close to home, you have many.
But it’s hard to say cost doesn’t matter but the lower the better.
Pre law is not a major. It’s an intention that one day I might go to law school. You can major in anything.
The obvious school in addition to UMD - assuming you are in the Baltimore / DC area is UDel. You can apply to those two and be done.
But you can add a JMU, Pitt If four hours ok and even a Binghamton.
If you want small or smaller, a St Mary’s, Christopher Newport, or Mary Washington. You have AU and GW too.
If you want an LAC, plenty of close ones abound such as Gettysburg, Dickinson, F&M, and more.
Define two things - budget (don’t say none but the lower the better - are your parents ok so ending $375-400k over four years plus another $300k for law ?
Or do they have a desired spend ?
But depending on the type of school you want (size, environment, cost), you can be done app wise pretty quickly.
And you can manor in anything for law school, including polo sci which you list as possible - and UDEL, UMD, and Pitt would all be fantastic and you’d be in at two, if not all three. Get that SAT to 1450 and submit to UMD. But you have a chance either way. For GW, it’s very different with its urban-ness. Get on their mailing list and demonstrate interest. Like UMD possible but not assured. Willing to pay in full will help. A lot !!
Good luck.
