PHOENIX — Chelsea Clinton and Bernie Sanders are headed to Arizona this week to campaign for Democratic presidential candidate Hillary Clinton.

Hillary Clinton’s campaign says Chelsea Clinton will attend an Arizona Democratic Party early vote rally on Wednesday at Arizona State University in Tempe, while Sanders will hold early voting rallies in Flagstaff and Tucson on Tuesday.

Hillary Clinton hasn’t visited Arizona since March as she focuses on battleground states, but the presidential race in traditionally Republican-leaning Arizona is seen as tightening.

Democrats believe they’ve got a shot of winning Arizona for the first time since Bill Clinton carried the state in 1996.

Republican nominee Donald Trump has held six rallies in the state since July 2015.
