Maryland has been reliably blue in presidential elections, voting for the Republican nominee just three times in the past half-century (for Richard Nixon in 1972, Ronald Reagan in 1984, and George H.W. Bush in 1988).

Support for Donald Trump has been low in the state, with Federal Election Commission data showing that 95 to 100 percent of donations in the affluent Washington, D.C. suburbs going to Hillary Clinton.

The numbers shown here were calculated by summing all donations to Trump and Clinton in both the general election and the primaries, then determining the percentage that went to each candidate. Statewide, only 10 percent of donations went to Trump, but his share was significantly lower in the Washington suburbs.
