Prince George’s, Montgomery, Baltimore and Baltimore City which are the largest counties voted massively in favor of Hillary Clinton giving her a 725,377 vote advantage out of those counties. Aside these, her wins in other counties such as Anne Arundel, Howard and Charles gave her additional vote advantage. On the other hand, Trump’s steady win margins in counties such as Harford, Frederick, Carroll, Washington, Cecil, St. Mary’s and Wicomico gave him a 116,503 vote advantage, nothing close to Clinton’s win.  This made Hillary Clinton gain an upper hand on Maryland.
