Mondale gradually pulled away from Hart in the delegate count, but the race was not decided until June, on "Super Tuesday III". Decided that day were delegates from five states: South Dakota, New Mexico, West Virginia, California and New Jersey. The proportional nature of delegate selection meant that Mondale was likely to obtain enough delegates on that day to secure the stated support of an overall majority of delegates, and hence the nomination, no matter who actually "won" the states contested. However, Hart maintained that unpledged superdelegates that had previously claimed support for Mondale would shift to his side if he swept the Super Tuesday III primary. Once again, Hart committed a "faux pas," insulting New Jersey shortly before the primary day. Campaigning in California, he remarked that while the "bad news" was that he and his wife had to campaign separately, "he good news for her is that she campaigns in California while I campaign in New Jersey." Compounding the problem, when his wife interjected that she "got to hold a koala bear", Hart replied that "I won't tell you what I got to hold: samples from a toxic waste dump." While Hart won California, he lost New Jersey after leading in polls by as much as 15 points.
