So, why did McCain do best, relative to George W. Bush in 2004, in states like #1. Tennessee, #3. Arkansas, #5 Oklahoma, #7 West Virginia, #9 Kentucky, and #10 Alabama?
Here's a map by counties, with counties where McCain improved relative to GWB in 2004 the most shown in reddest red.
Before reading onward, can you figure out why this pattern exists?
The pattern should be quite obvious to anybody who has read David Hackett Fischer's Albion's Seed on the four types of Brits in America.
John McCain, a pugnacious Scots-Irishman, did best in counties full of pugnacious Scots-Irishmen.
Tennessee, home of Andy Jackson, was the state where McCain improved on Bush's vote the most.
(The other four states in McCain's Most Improved Top Ten are driven by obvious special factors: #2 Louisiana by the decline in number of blacks due to the hurricane; #4 Alaska by Palin's status as a Favorite Daughter; #6 Massachusetts by favorite son John F. Kerry no longer being on the ballot; and #9 Arizona by McCain being a Favorite Son.)
