Des Moines Register, one of the best over there. Released today: Senate - Greenfield 46%, Ernst 43%; POTUS - Trump 46%, Biden 45%. Both within margin of error. Trump carried Iowa by 9% in 2016. Ernst won her Senate seat in 2014 by 8%. Poll only includes registered voters who intend to vote. Lots of money from both sides pouring into this one. Women are fueling the closing gap for both Democrats by large margins.
