Most Republican strength lies mainly in northwest Arkansas in the areas around Fort Smith and Bentonville, and especially in North Central Arkansas around the Mountain Home area where voters have often voted 90 percent Republican. The rest of the state is strongly Democratic, especially Little Rock and the areas along the Mississippi River. Arkansas has only elected one Republican to the U.S. Senate since Reconstruction, Tim Hutchinson, who was defeated after one term by Mark Pryor. The General Assembly has not been controlled by the Republican Party since Reconstruction and is the fourth most heavily Democratic Legislature in the country, after Massachusetts, Hawaii, and Connecticut. Arkansas is also the only state among the states of the former Confederacy that sends two Democrats to the U.S. Senate and the overwhelming majority of registered voters in the state are Democrats. The state is socially conservative – its voters passed a ban on gay marriage with 74% voting yes, the Arkansas Constitution protects right to work, and the state is one of a handful that has legislation on its books banning abortion in the event Roe vs. Wade is ever overturned.

In Arkansas, the lieutenant governor is elected separately from the governor and thus can be from a different political party.

Each officer's term is four years long. Office holders are term-limited to two full terms plus any partial terms prior to the first full term. Arkansas gubernatorial terms became four years with the 1986 general election; before this, the terms were two years long.

Some of Arkansas's counties have two county seats, as opposed to the usual one seat. The arrangement dates back to when travel was extremely difficult in the state. The seats are usually on opposite sides of the county. Though travel is no longer the difficulty it once was, there are few efforts to eliminate the two seat arrangement where it exists, since the county seat is a source of pride (and jobs) to the city involved.
