Maryland will be swing territory, IMO, with the Democrats split on the short term (extending the circumstances around the 1966 gubernatorial election to a wider application). Old school Marylanders, especially on the Eastern Shore, might as well have been from Mississippi given their attitudes on race at the time (indeed, many affected Dixie accents you could cut with a saw). They'd be just about neck-and-neck with more progressive elements around Baltimore and the surrounding counties (see, for example, Hyman Pressman as a leader) in the Democrat ranks. Republicans, led by Theodore McKeldin, Rogers Morton and (heaven help us all) Spiro Agnew would have the balance of voters. It would all depend on who's sore at whom when as to how any given state-wide results would go. Maryland would be one of the most difficult states to forecast at least on the short term. The thing is, with Maryland's long history of close relations with the Democrats (for as long as I've been alive, the Dems' primaries in MD have been tantamount to the general election), I can't see the state going Republican even mildly / even for a short term. And I say all this as someone who grew up in suburban Baltimore in the 1950s and 1960s.
