The disproportionate power enjoyed in the Senate by small states is playing a growing role in the political dynamic on issues as varied as gun control, immigration and campaign finance.
The Constitution has always given residents of states with small populations a lift, but the size and importance of the gap has grown markedly in recent decades, in ways the framers probably never anticipated.
What is certain is that the power of the smaller states is large and growing. Political scientists call it a striking exception to the democratic principle of “one person, one vote.” Indeed, they say, the Senate may be the least democratic legislative chamber in any developed nation.
There is a widening demographic split, too, with the larger states becoming more urban and liberal, and the smaller ones remaining rural and conservative, which lends a new significance to the disparity in their political power.
