When we look at the changes in the population of Maryland over the past 50 years it is apparent that Baltimore City and Allegany County are the only two jurisdictions to lose population and the Washington suburbs and Central Maryland counties had large increases. This reality has changed Maryland politics from Republican to Democrat. In the 1970s many Republicans were moderate and liberal Republicans. They have all mostly shifted to the Democrat Party. Nowhere has this been more true than Howard County which was a conservative county in the 1960s and 70s but the development of Columbia has made the County "deep blue."
