Which States Swung Most?

After examing the data from Dave Leip's Atlas of U.S. Presidential Elections, I made a list of the ten states where the Republican margin increased most (or the Democratic margin decreased most). They are:

State	Amount of swing
Alabama	10.8%
Tennessee	10.5%
New Jersey	9.6%
Hawaii	9.6%
Oklahoma	9.3%
Rhode Island	8.4%
New York	7.7%
Connecticut	7.2%
Louisiana	6.9%
West Virginia	6.5%

The list includes quite a few “blue” states.

Now let's look at the opposite: the ten states where the Democratic margin increased most (or the Republican margin decreased most). They are:

State	Amount of swing
Vermont	10.3%
Montana	4.5%
Alaska	4.2%
D. C.	3.9%
Oregon	3.5%
Maine	2.9%
New Hampshire	2.6%
Colorado	1.9%
Washington	1.7%
Idaho	1.4%

It looks like the Northeast Corridor and Bible Belt swung right and the Northwest (both Pacific and Mountain) and northern New England swung left.
