Joe Biden and Donald Trump each won the White House by razor-thin margins in key states. Now they each must try to rebuild their once-winning coalitions. Trump's next task is to complete a takeover of the Republican National Committee with his preferred leadership team. They are then expected to work on trying to catch up to Democrats' fundraising and organizing network. Biden will deliver his State of the Union address Thursday before leaving Washington to campaign in key battleground states. Both men will campaign in Georgia on Saturday. Biden's team believes its head start on building campaign teams in key battleground states will pay off in November.
