Denmark is a constitutional monarchy with only one house of parliament. Citizens will be choosing both the executive and legislative arms of the government in the election. The Danish system relies on negotiations between parties, and coalitions are the norm. In 2011, nine parties — none of which received more than 26.7 percent of the vote — were voted into the parliament. The last time a party won an outright majority in the legislature was in 1903. The large number of parties and frequency of coalitions has led to the formation of two voting blocs, the right (known as the blue bloc) and the left (known as the red bloc). Whichever bloc has the most votes is likely to produce the new government from its constituent parties. Currently, polls show a virtually even split between the blocs, though the incumbent red bloc has gained some momentum recently.
