Good because apparently it was a huge debacle!
A little less than a month after long lines—and waits—defined the Arizona primary, the Democratic Party, and both the Hillary Clinton and Bernie Sanders campaigns, will sue the state over the insufficient number of polling locations, according to The Washington Post.

The lawsuit, which calls for the U.S. District Court of Phoenix to review voting plans ahead of the November election, will be filed on Friday. “[Arizona’s] alarmingly inadequate number of voting centers resulted in severe, inexcusable burdens on voters county-wide, as well as the ultimate disenfranchisement of untold numbers of voters who were unable or unwilling to wait in intolerably long lines,” according to the lawsuit.

The lawsuit will be brought “on behalf of the Democratic National Committee, the Democratic Senatorial Campaign Committee, the Arizona Democratic Party, and several Arizonans.” Democratic officials told the Post that the Clinton camp plans to join after it’s filed, as will Sanders, according to one of his senior aides.
