As the next decade approaches, the US stands at a historic crossroads regarding both domestic and foreign issues. The 2020 presidential and congressional elections will to a large extent determine whether the current trends of populism, polarization, and incitement coursing through American society, and of withdrawal from international leadership, will continue or come to an end; whether the phenomenon of “Trumpism” will persist or be remembered as an aberration; whether the political and ideological gaps between Democrats and Republicans that have paralyzed the administration will narrow; and whether the economic boom of the last few years will go on or the US will enter a recession. Demographic shifts are changing the face of the US, and in the course of the decade they will have a significant impact on major political, social, and economic issues.
