Washington

A very important one. Washington skyrocketed with Roosevelt's New Deal and has kept growing fast as the government grows fast as well. Metropolitan areas based on "traditional" economy, such as Baltimore, cannot compete with that.
On 2000, both Washington and Baltimore MSAs were merged into a single CSA, where Washington is by far the most important partner. The final blow on Baltimore came on 2012, as Washington (city proper) overtook Baltimore for the first in history.
