The explanation for Charles County’s sudden swing towards the Democrats is quite simple: blacks from the DC area are moving further out into the suburbs. past PG County into Charles. The change in Charles County has been so drastic that when I first wrote back in 2005 about creating a State of New Columbia (that combined DC with its heavily Dem suburbs in MD and VA) I kept Charles County in MD because it wasn’t Democratic enough.
Yeah, the change is stark. In 2000, almost 70% of Charles County’s population was White. In 2010, it plummeted to 50% (the Black population went from 26% to 41%). Before the decade is out, it will be Black majority. What’s so sad is that they flee out of DC or PG County and carry the SAME voting habits that made those places hellholes. This contrasts with decades ago when White urbanites would discard their Democrat habits moving to the suburbs (although many of those folks have since been going in the wrong direction politically in more recent years).
