George W. Bush Republican Barack Obama Democratic The 2008 United States presidential election in Maryland took place on November 4, 2008, and was part of the 2008 United States presidential election.

Maryland was won by Democratic nominee Barack Obama by a 25.4% margin of victory.

Here are their last predictions before election day: Obama won every single pre-election poll, each by a double-digit margin of victory and at least 51% of the vote.

In 1980, it was 1 of only 6 states to vote for Democrat Jimmy Carter over Republican Ronald Reagan.

Republican presidential candidates typically win more counties by running up huge margins in western Maryland and the Eastern Shore.

However, they are usually swamped by the heavily Democratic Baltimore-Washington, D.C. axis, which casts almost 75% of the state's vote.

These areas, which contain 1.5 million voters combined, make it extremely difficult for a Republican to win Maryland.

In 1984, for instance, Ronald Reagan only carried Maryland by crushing Walter Mondale in Baltimore County and narrowly winning Montgomery.
