[edit]

Macon County was formed on January 19, 1829, out of Shelby County. It was named for Nathaniel Macon, a Colonel in the Revolutionary War.[3] Macon later served as senator from North Carolina until his resignation in 1828. In 1830, future US President Abraham Lincoln and his family moved to Macon County.

Geography

According to the US Census Bureau, the county has a total area of 586 square miles (1,520 km2), of which 581 square miles (1,500 km2) is land and 5.2 square miles (13 km2) (0.9%) is water.[4]

Macon County is primarily flat, as is most of the state and all of the surrounding counties, the result of geological activity during the Pleistocene epoch. During the Illinoian Stage of the Pleistocene, the Laurentide Ice Sheet covered about 85 percent of Illinois, including the Macon County area. The subsequent thaw of the region and retreat of the ice sheet left central Illinois with its present characteristic flat topography.[5]

Because of its central location, Macon County is often referred to as "The Heart of Illinois."[6]

Politics

[edit]

In its early years Macon County favored the Democratic Party, voting for it in every election through 1860. Republican Abraham Lincoln won the county in the 1864 election, and from then until the Great Depression Macon County became solidly Republican, only giving a narrow plurality to Woodrow Wilson in 1912 when the GOP was divided by Theodore Roosevelt's splinter–party run.

The FDR-era New Deal saw the county become more amenable to the Democratic Party again due to its strong industrial base. Macon County voted for the winner in every election from 1920 through 1996 save in 1960, 1968, and 1988, in two of which it voted for a losing Democrat over a winning Republican (Humphrey over Nixon in 1968 and Dukakis over George H. W. Bush in 1988). In 2000, Macon voted for a losing Democrat for the third time since the New Deal, as Al Gore narrowly held the county, but since then the county has once again trended Republican, as George W. Bush carried the county over John Kerry in 2004 with the same vote share as Reagan in his 1984 national landslide. Illinois native Barack Obama did carry the county with a plurality in his sweeping 2008 triumph, but was convincingly defeated by Mitt Romney in the county in 2012. In 2016, Hillary Clinton got the lowest vote share of any Democrat since George McGovern; and while Joe Biden improved on her vote share in 2020, he still failed to match McGovern's percentage.
