In Tennessee, too, the Democratic winner of the popular vote could wind up receiving the second largest number of delegates.

From campaigndiaries.com:

* The 9th district which is 59.7% black (which means an even higher proportion of Democratic primary voters). It is also a 6 delegate district, and Obama should be able to break the 59% he needs for a 4-2 split.
* The first, second and third districts all allocate four delegates. And while Clinton is likely to win big in all of them, she needs to break 62.5%. That will obviously be very hard for her to accomplish, especially given that Obama can count on a minimal black base in all those places, so that she could be forced to come out of these 3 districts with a 6-6 split.
* The 5th district is 23% black and has 6 delegates. Obama is likely to win there, and he could be forced to split the delegates. But he is more likely to break 59% than Clinton is to break 62% in the first 3 districts.
* That leaves Clinton with the 4th, 6th, 7th districts to get any sort of delegate lead. All of these have 5 delegates, which makes it near impossible for her to win by a big enough landslide to get a 4-1 edge (once again, the black vote should provide Obama with a strong base). In other words, these three districts combined could give Clinton a 3 delegate lead -- one each.
* Finally, the 8th district looks to be more disputed between the candidates. It is a 5 delegate district, so that the winner will get an extra delegate even if he only wins by a vote.
* The bottom line: Obama could lose the state by 15% or more but tie Clinton on the district delegate count. By opening up a 2 delegate margin in the 9th and perhaps the 5th district while forcing Clinton to split the delegates in her own strongholds (the first 3 districts), Obama would at worst trail Clinton by 1-2 delegates, at best lead her by as much. And all of this while losing the popular vote by 15%
