Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, offers insights on US politics:

First question. What do the results of the Georgia Senate election mean?

Well, this is a real game changer for President Biden. He came into office with the most progressive agenda of any president in modern history and the Republicans controlling the Senate were prepared to block all of that. That meant no education spending, no healthcare spending, very little green energy spending and probably no stimulus spending, further COVID stimulus spending this year. Now the Democrats seem to have a majority in the Senate, as well as the House of Representatives. All of that can get done as well as tax increases in order to finance it. The concern now for the Democrats is overreach that could lead to backlash. They have very thin majorities in the House, and the trend has been that in the first midterm for a new president, you almost always lose seats in the House. Democrats can't really afford to lose too many. That may cause them to moderate some of their plans.
