DES MOINES, Iowa (AP) — In 2008, Barack Obama won the hearts of Iowa Democrats. Today, his supporters are looking more pragmatically for someone who can simply seize the presidency from Donald Trump in 2020. Niki Neems, a Democratic activist in Iowa city, says that ideally she would want to fall in love with the new candidate the same way as she did with Obama.
