Wisconsin voters have shown unpredictability by swinging between parties in recent elections, making the state a critical swing state for the 2024 presidential election. Trump's relationship with Wisconsin Republicans is complex despite having a hold on the GOP.

Illinois Republicans are fully backing Trump for the nomination, showcasing unity despite previous losses and internal party turmoil.
