Ian Bremmer's Quick Take: Hi, everybody. Ian Bremmer here, and a happy Monday to you. Want to turn to US domestic politics for this week's Quick Take in part because there's been a surge in the GOP among the candidates. We've had Trump way out in front, and Florida Governor Ron DeSantis as the major challenger pretty much for the last several months until this last week, with an outsider Vivek Ramaswamy in a couple of polls showing up as number two. Certainly enjoying a surge. So thought it was worth taking a little bit of a look at him.
