See http://www.thegreenpapers.com/Definitions.html | | | | | | | | | | | | | ***- Turnout defined as 2008 primary vote as share of 2004 Kerry general election vote. | | | | | | | | | | | | | **** - Results reflect victory of Clinton over Obama or Obama over Clinton among whole field. Note that as the number of other candidates in the field increases, the size of this number likely decreases. Importantly, John Edwards received non-negligible vote totals through Super Tuesday. So, adjustments might be necessary to compare these states to post-Edwards states. For instance, among Clinton or Obama voters in Tennessee, Clinton won by 14.3%. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
