As each state makes national headlines with its redistricting pushes, you may have heard the term “gerrymandering.” So what is it?

Gerrymandering is the process of manipulating electoral boundaries in order to favor one political party or class.

“Elections are supposed to produce results that reflect the preferences of voters. But when maps are gerrymandered, politicians and the powerful choose voters instead of voters choosing politicians,” the Brennan Center for Justice explains.

The origin of the word goes hand-in-hand with its history in politics.

The Library of Congress says the term was first used on March 26, 1812, in the Boston Gazette, after a redrawing of Massachusetts State Senate election districts. The governor at the time was Elbridge Gerry, and although the redrawing was done under the Democratic-Republican Party, he signed the bill approving the maps.

The ‘mander’ portion of the terms relates to how those districts looked. One of the remapped districts in the Boston area was said to resemble a salamander.

The districts were “brought to life” as a mythical salamander or dragon in a political cartoon by artist Elkanah Tisdale.

The term "gerrymander" stems from this Gilbert Stuart cartoon of a Massachusetts electoral district twisted beyond all reason. Stuart thought the shape of the district resembled a salamander, but his friend who showed him the original map called it a "Gerry-mander" after Massachusetts Governor Elbridge Gerry, who approved rearranging district lines for political advantage.

Proposition 50

The latest redistricting push comes after President Donald Trump asked Texas to redraw their maps to bring five more Republicans to Congress in the 2026 midterm election.

Because of that, Gov. Gavin Newsom and California’s Democratic leaders have fired back with a plan to send more Democratic representatives to Congress.

But Texas and California’s situations are very different.

In Texas, lawmakers in the state’s legislature have the power to redraw the maps, with approval from the governor. In a state that’s widely represented by Republicans, it was not a difficult feat. Gov. Greg Abbott signed the new maps into law on Aug. 29.

In California, however, the congressional maps are decided by an independent commission.
