Despite record-shattering fundraising numbers across the map, Democrats’ hopes of a net gain of three seats if Biden wins, or four if Trump wins, to give them a Senate majority were slipping. Those hopes could now depend on Georgia, where at least one and potentially two Senate races are headed to runoffs. Results in Maine and North Carolina — two top Democratic targets — remain outstanding.Two Democratic Senate challengers, Jaime Harrison in South Carolina and Amy McGrath in Kentucky, raised about $200 million combined to challenge Republican Sens. Lindsey Graham and Mitch McConnell. Both were blown out. Democratic challengers in Iowa and Montana also lost.
