They are normally at each other's throats but for now Hillary Clinton and Bernie Sanders are joining forces, along with the Democratic Party, to file a lawsuit against the state of Arizona over long voting lines at the state primary last month. As the Washington Post reports, some voters waited in lines for as long as five hours.

The lawsuit, which will be filed on Friday, focuses on Maricopa County, the state’s most populous county, where voters faced the longest lines on March 22 during the Democratic and Republican primaries after the county cut the number of polling places by 85 percent since 2008.

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,” the lawsuit says.

The lawsuit claims that black, Hispanic and native American voters in Maricopa County were particularly hard hit, with not enough voting places compared to districts with more white voters.

This is not the first lawsuit that Democrats have launched. Suits have also been launched in Ohio, North Carolina, Virginia and Wisconsin.
