I made the On which date will a U.S. presidential candidate from each major party clinch his or her nomination? market. For some reason, only the Republican results display. I’ve filed a bug report, but I also wonder if there’s anything I might have done wrong in setting this up to keep the Democrats from appearing. Any suggestions? Thanks.

Nope, this type of market only shows the one stuck in the graph. Will get a fix out soon. Thanks for pointing this out.
