DES MOINES, Iowa (AP) – When Joe Biden was last in Iowa, his campaign was on the verge of collapse and he was soundly trounced in the caucuses. He returns Friday as the Democratic nominee, believing he’s just days away from becoming president-elect. Iowa is among the clutch of GOP-leaning states that Biden is trying to bring back into the Democratic column. He’ll also swing through Wisconsin on Friday while his running mate, Kamala Harris, courts voters in Texas. Trump, meanwhile, is playing defense in Michigan and Wisconsin. The president and Biden will both be in Minnesota, a longtime Democratic state that Trump is trying to flip.
