2014

In a repeat of the 2002 pattern, a surge of Republican votes concentrated in areas outside the Washington suburbs placed a GOP governor inside the Maryland statehouse. Larry Hogan’s biggest margin of victory was 140,000 votes, in his home county of Anne Arundel.

2010

In the last governor’s race won by a Democrat, Baltimore city and Montgomery and Prince George’s counties alone provided a margin of almost 400,000 votes, more than enough to carry Gov. Martin O’Malley to a second term.

2002

In 2002 Maryland voters elected their first Republican governor in a generation. Strong Republican margins from Baltimore, Howard and Anne Arundel counties, and in rural areas, more than countered Democratic wins in the Washington suburbs and the city of Baltimore.

Margins by urban regions

Who wins in the Maryland governor’s race depends on swing voters in suburban counties, as well on the balance of voter turnout across the state. Here’s a look at the different roles played by counties across the urban landscape.

Large urban

These three large counties, home to Maryland’s biggest blocks of minority voters, are the state’s Democratic stronghold.

Suburban

The largest Republican margins usually come from among these nine counties. But swing voters can change the size of wins, and determine elections.

Rural

Reliably Republican, the 12 least-urban counties have the fewest votes, but they can be key when margins in suburban and urban counties are close.
