NEWTON, Iowa (AP) — The Senate impeachment trial schedule means this may well be the last full weekend of campaigning in Iowa for some Democratic candidates. Four senators in the race will serve as jurors in the trial of President Donald Trump. They are Elizabeth Warren of Massachusetts, Bernie Sanders of Vermont, Amy Klobuchar of Minnesota and Michael Bennet of Colorado. That’s left their campaigns scrambling to come up with ways to keep them on voters’ radars in Iowa and the early-voting states. It could also be an advantage for two of their rivals, former Vice President Joe Biden and Pete Buttigieg, the former mayor of South Bend, Indiana.
