Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, DC shares his perspective on US politics:

How does Nikki Haley's campaign affect the state of the 2024 race?

Nikki Haley, the former South Carolina governor and UN Ambassador under the Trump administration, announced her 2024 presidential campaign this week, becoming the first Republican to challenge former President Donald Trump. Haley said in 2021 that she would not run for president if Trump were to do so, a comment that has already drawn flak from the former president, but her shift in approach reflects how far Trump has fallen within the GOP over the last two years. Trump has looked much weaker in 2022 than he did in 2021, and weaker still since his candidates largely flopped in the midterm elections last November. The announcement of his presidential bid soon after drew big headlines for a day before being largely forgotten, and he had difficulty consolidating support ahead of his first campaign event in South Carolina last month.
