It almost happened last time, and if the population estimates hold, it will most certainly happen next time.
We're talking about the number of Congressional seats allocated to Idaho as part of apportionment.
The recent U.S. Census Bureau population estimates show that Idaho, along with Arizona, Texas and Florida would each add one seat while California, Minnesota, Illinois and New York would each lose a seat.
As a result, Idaho's Congressional delegation would be at five. This also means Idaho would gain one vote in the Electoral College.
The Gem State was just 28,000 citizens away from gaining the extra seat in the 2020 apportionment. The process will happen again in 2030.
Seven years is a long time and population estimates can change quickly. Still, it is interesting to think about what a third Congressional district in Idaho could look like. Would the Boise-area be its own district or be divided up? The state's independent redistricting commission would decide.
