Republicans should have every reason to be satisfied. They won support from voters of every ethnic background as identity politics was comprehensively rejected. Their down-ballot candidates fared well, outperforming President Trump nationally and in key states. The GOP made gains in the House and ought to hold the Senate.

Yet, incredibly, they risk throwing it away. At best, their refusal to accept the presidential election result looks petty and graceless and risks what ought to be two comfortable Senate wins in Georgia. At worst, it undermines the legitimacy of America’s institutions.
