House Republicans are privately concerned about replacing President Biden at the top of the Democratic ticket, fearing it could lead to a GOP loss in November. Meanwhile, there are debates on Biden's performance post-debate, with some believing he will stay as the candidate despite concerns. In contrast, despite international preference for Biden, Trump's debate victory has spurred world leaders to prepare for a potential second Trump administration. Speculation on Biden's future participation in the election race suggests it hinges on discussions with his wife Jill Biden, amid reports of internal deliberations and a desire for a new Democratic presidential candidate.
