After a long election season, we have at least some clarity regarding control of the presidency and the U.S. Senate. At this point, barring successful litigation or recounts by President Donald Trump's campaign in multiple jurisdictions, Joe Biden is the president-elect. Control of the Senate, on the other hand, will not become clear until Georgia holds its runoff election in early January.
