Seeking Blue City from Red South

Single mom to an upcoming Kindergartner seeking refuge from red state.

Want to rent 1-2 bedroom around $2500-3000 or less. Small dog friendly.

Must have good schools. Bonus if it has dual language so my son can learn Spanish.

Only want to be in blue cities.

Would love walkable city and/or near public transportation so I wouldn’t have to rely on car for a change of pace.

Appreciate your help. I know my budget makes it difficult.
