1. California (+14.8%)
2. New Jersey (+11.4%)
3. North Carolina (+11.1%)
4. Virginia (+11.0%)

47. Wisconsin (+0.4%)
48. Maine (-0.1%)
49. West Virginia (-1.4%)

Actually, the colors should be the other way around. Meh. I went off of the OP and was messed up. Sigh.

Disregard my last list. Here are the top and bottom ten swings by %VAP.

1. North Carolina (+6.0%)
2. District of Columbia (+5.2%)
3. Virginia (+5.2%)
4. Mississippi (+4.8%)
5. Rhode Island (+4.7%)
6. South Carolina (+4.1%)
7. Alabama (+3.6%)
8. Indiana (+3.6%)
9. Maryland (+3.3%)
10. Georgia (+3.0%)
...
42. Idaho (-1.6%)
43. Arizona (-2.2%)
44. Oklahoma (-2.3%)
45. Maine (-2.6%)
46. West Virginia (-3.4%)
47. Wisconsin (-3.4%)
48. Alaska (-3.8%)
49. South Dakota (-5.4%)
50. Oregon (-5.5%)
51. Utah (-7.7%)

21 States decreased turnout, 2 remained the same, and 28 increased. California, which no longer leads the list, still came in 12th overall, right behind New Jersey, which was second.

Utah blows my mind a little.  Mormons seem like the sort of conformist cultural subset that would have high voter turnout even among lower middle class people.

Not only was it low, but it fell the most of any state from 2004.
