US midterm elections have traditionally been a referendum on the president, now Joe Biden. That's one option, Ian Bremmer explains in a special episode of GZERO World in front of a live studio audience.
Yet, even Biden wants the vote to be all about his predecessor, Donald Trump, who still dominates the GOP. Option No. 2.
There's a third option: culture wars. Yes, things like abortion rights or CRT.
Whatever the midterms are all about this time around, one thing is clear: the result will have global ripple effects. On US relations with Russia, China, and American democracy itself.
