GOP's 2026 outlook darkens: Trump's influence, key issue approval decline.

• Donald Trump's strategy of leveraging voter anxiety helped Republicans win in 2024, but its effectiveness for 2026 is questioned.
• Republicans have experienced recent election setbacks, including losses in Miami and a historically Republican district in Georgia.
• Trump's influence within the GOP shows limits, as seen in his inability to sway Indiana senators on a new congressional map.
• Public approval for Trump's handling of the economy, crime, and immigration has significantly declined since March.
• Republicans are concerned about potential midterm losses, similar to 2018, especially with issues like affordability and rising healthcare costs.

Why It Matters: Trump's declining influence threatens Republican control in future US elections.
