What will decide the 2024 US election?

On Monday voters in Iowa begin the nationwide process of deciding which candidates will be on the ballot in November’s US presidential election. Most expect it to once again be a competition between Joe Biden and Donald Trump. Control of the House of Representatives, the Senate and various state governments will also be decided. So, how is this year’s election cycle likely to unfold, which issues will dominate, and how will this election differ from those we’ve seen before?
