North Dakota and South Dakota have a combine voter turnout of 454,000 and California with 11 million both get two senators per state.
Or put differently, North Dakota and South Dakota has 4% of the population of California, and get twice the senators.
It should be noted that North Dakota and South Dakota, which has more than the usual number of conservatives who bitch about federal intrusion, uses much more federal funds than they pay.
They actually get much more tax money from the federal government than are paid by that state's property taxes.
If there was a civil war, the mid-west and south-east economies would be screwed.
