Dallas County is governed by a Commissioners Court. The Dallas County Commissioners Court consists of the County Judge (the chairperson of the Court) who is elected County-wide and four Commissioners who are elected by the voters in each of four districts.

The Commissioners Court is the policy-making body for the County; in addition, the County Judge is the senior executive and administrative position in the County. While the cities in the County handle many tasks in local government, the County holds responsibility for the following:

"The Commissioners Court sets the County tax rate, adopts the budget, appoints boards and commissions, approves grants and personnel actions, and oversees the administration of county government. Each commissioner also supervises a Road and Bridge District. The Commissioners Court also approves the budget and sets the tax rate for the hospital district, which is charged with the responsibility for providing acute medical care for citizens who otherwise would not receive adequate medical services."[3]

The total 2010 fiscal year budget is approximately $871 million USD.[4]

Dallas County has voted for the Republican presidential candidate in almost every election since 1960; the only exceptions being in 1964 and 2008. More recently however, it has gradually shifted more Democratic in recent elections. The Democratic gains are primarily due to the city of Dallas, which has become a stronghold of that party.
