As of Monday, Greenfield’s average lead in the RealClearPolitics average was 4.8%, while Biden was up by a more meager 1.2%. Perhaps tellingly, most of that difference comes from Ernst underperforming Trump — her average polling share stands at 42.5%, compared to Trump’s 46.3%. So it makes sense that, despite his sagging national fortunes, Ernst generally is still trying to frame herself as a firm ally of the president.

For Senate Democrats, last quarter’s fundraising numbers were truly historic. For the period spanning from the start of July to the end of September, Democrats in key Senate contests across the country raised a combined $265 million. In Iowa, Greenfield set a state fundraising record — her $29 million quarterly haul was roughly four times what Ernst raised. Candidate fundraising isn’t everything — outside groups are also spending heavily in the state, and Senate candidates in past cycles have lost to lesser-funded opponents — but going into the final stretch of the campaign, Greenfield seems to have the momentum…

The soybeans gaffe seems symptomatic of Ernst’s reelection effort: in 2014, playing up her rural persona and vowing to “make ‘em squeal,” she rode her motorcycle onto the national scene as a political outsider. After a term in the Senate, and running in a totally different environment, Ernst’s campaign seems to have lost some of that 2014 zeal. Though Iowa hasn’t ousted an incumbent senator since 1984, we see Greenfield with the upper hand. The race is moving from Toss-up to Leans Democratic.
