I guess you would consider the Alaska Democrats sore losers as well.  In the Democratic Primary for US Senate, Ray Metcalfe won but he wasn't the choice that the Alaska Democrats wanted - so their pick is running as an independent - http://www.adn.com/politics/2016/09/07/with-joe-miller-now-running-alaskas-u-s-senate-race-is-even-more-topsy-turvy/  "The Democrat in the race, Ray Metcalfe, is a former Republican state legislator who founded his own party — the Republican Moderates — before becoming a Sen. Bernie Sanders booster at odds with state Democratic leaders.

Meanwhile Democratic leaders tried to place Margaret Stock, once a Republican but now an independent U.S. Senate candidate, on their primary ballot. That effort failed, but Stock is now part of the Democrats' "coordinated campaign," which gives her access to the party's voter data and staff. And Republicans accuse her of "charading" as an independent and "hiding" her true affiliation with Democrats."
