In Colorado, there's a multi-initiative war between business and labor interests. Each side is sponsoring multiple measures. But there are talks underway, with some participation by Gov. Bill Ritter, aimed at avoiding a full war in November. The Denver Business Journal has details.

ADDED, 9/21: More details on the talks from the Rocky Mountain News, which even has some documents on the deal-making.
