Yes, which is why I also calculated the per capita household median income, also adjusted by cost of living plus number of average residents. The top ten include three Red states (#1 North Dakota, #4 Wyoming, #8 Nebraska) and two Purple states that are well on their way to becoming Red states (#2 Iowa & #10 Ohio), plus another solidly Purple state (#9 Wisconsin). The four Blue states are #3 Minnesota, #5 New Hampshire, #6 Illinois, #7 New Jersey. The Big names for Red States/Blue States are well down the list, Texas at #36 and California at #49.
Don't forget that this ranking is based on votes for multiple offices, including governor, over a sixteen year period. Over those sixteen years, West Virginia voted Republican 75% of the time for the House, 29% of the time for the Senate, 25% of the time for Governor, and 100% of the time for President. As Democrats that are personally popular retire or are finally defeated, West Virginia will shift into the Red column. At this point, it looks like it's just a matter of time.
