Are Politicians Still Chasing the Middle Voters?

The Median Voter Theorem suggests that in a two-party, majority rule election, parties will have an incentive to move towards the median voter so that they can get the most amount of votes possible. But what happens when candidates change who the voters are instead?

As politics becomes more polarized and extreme, at least seven states have redrawn their congressional districts to help the party in power prior to the 2026 midterm elections, most favoring Republicans. This process of gerrymandering has reduced electoral competition, meaning that some individuals and groups are losing voting power. It has also created an interesting problem for the Median Voter Theorem. 

Neither the voters nor the candidates preferences have shifted. Instead, the distribution of voters has changed, shifting the location of the median voter and therefore, candidates vote-maximizing strategies. Redrawing the districts moved the median voter closer to the party in power, creating a margin of safety in case of abstention and making it unnecessary for incumbent candidates to moderate their policies. In Louisiana's 6th district, the Black voting population fell from 53% to 25%, shifting the median voter from a liberal to a more conservative voter, reducing the Republican candidate need to appeal to Black voters. 

Politicians are still trying to maximize votes, but by changing district boundaries, they changed the group they need to appeal to. If politicians can choose the voters they need to win, then they may not need to chase the moderate median voter anymore, which can have extreme effects on future elections and the shape of politics as a whole in America.
