“Senate Democrats and campaigns have been circulating polling from a liberal outside group showing President Biden hurting their candidates in comparison to other potential nominees,” Semafor reports.
“While Senate candidates remained in strong shape overall in relation to Biden, with an average 55% to 45% lead over their opponents, their lead expanded modestly with Kamala Harris atop the ticket (56% to 44%) and slightly more with Gretchen Whitmer (57% to 43%).
