A terrific summary of the main candidates' positions on over two dozen different issues are clearly presented on this table (flickr.com), which is a graphic version of this table (2decide.com).
Granted, the table doesn't get into specifics or degree of intensity of support, but it's definitely a helpful start when the field is so heavily populated.
And I'm shocked...shocked, I tell you, to realize that of all the candidates, Dennis Kucinich, the boy from my own state of Ohio, most closely matches my own positions (as far as I can tell...he and I seem to disagree only on capital punishment).
