This bill matters because it would fundamentally change how political power is distributed among the states in the U.S. House of Representatives. If it becomes law, states with large non-citizen populations—often those with significant immigrant communities—would likely see their number of representatives reduced. This could shift influence away from these states and towards states with proportionally more citizens. Voters should care because it could alter who represents them in Congress and how much say their state has in national decisions, impacting everything from federal funding to policy priorities. If it doesn't pass, the current system of counting all residents for apportionment will continue.
