Jon Lieber, Eurasia Group's head of research and managing director for the firm's coverage of United States political and policy developments, shares his perspective on US politics from Washington, DC.

What we're watching in US Politics this week? The big story is the debates.

The debate about the debates was going to be a prolonged affair given some uncertainty about either candidate's desire to face off against each other. And while earlier in this week it looked possible that the US might not have any presidential debates the first time in recent memory. Instead, now we know we're going to have at least two, one in June and one in September.
