Like many Iowans, Roxanne Gusthaveson still isn’t sure whom she’ll caucus for next week. But her focus on finding a candidate who can beat President Donald Trump means that Joe Biden is probably her guy. Gusthaveson has noted the former Vice President’s rhetorical meanderings, sees “the hiccup in his step” since he last sought the Democratic Party’s nomination in 2008, and would prefer if he and his family weren’t enmeshed in the ongoing impeachment drama in Washington.
