Biden v Trump II: a rematch with few historical precedents

For the first time in more than 50 years, Republicans will rerun a candidate who lost a presidential election - and even longer since a presidential candidate faced a true rematch

When Joe Biden and Donald Trump secured enough delegates to lead the Democratic and Republican party presidential tickets in November, they confirmed what many voters expected but fewer actually wanted: a redo of the 2020 election.

Republicans skeptical about giving Trump a second shot tried in vain to elevate a viable primary opponent. Powerful donors, including the Koch-aligned Americans for Prosperity Action, poured money into former South Carolina governor Nikki Haley's campaign, but Haley was unable to claw enough support away from Trump to pose a threat to the former president.
