Baltimore, like most of Maryland, is hopeless for Republicans. There are just too many people dependent on the federal government for their income. Some of it is welfare type money but far more is jobs related. So many people work for the feds directly or for a company with lots of federal contracts, that the big counties near DC and Baltimore City are almost recession proof.
If Maryland were a thousand miles from DC and had the same anti-business policies, it might rival the poorest states in the country.
I "lived" there in "monkey" county for 30 years before escaping. Maryland is THE Freak state. It is truly hopeless there. Escape while you are still allowed to do so.
