(This graph will be more clear full size: click once or twice for full resolution.)
This post gives an alternative view of the top candidates in both parties in the first five primary and caucus states. The data are the same as in my state-by-state view of the primaries (see the links in the column to the right), but here you can see each candidate across all five states. This allows easy comparison of one candidate across all states (reading across each row), as well as across candidates within states (reading down each column).
The dates of each state's primary or caucus are what is currently expected, but are subject to change.
