The 2024 presidential election is still several years away, and at this point it is impossible to say with any degree of certainty who will replace Doge and Shib as the two major party candidates. That said, it is possible that two new alternatives, Bonk and Retik, may enter the fray and possibly replace Doge and Shib in the 2024 race.
Bonk is a pro-business populist who has risen to national prominence on the back of his anti-establishment message and anti-corruption promises. His message has resonated with both conservatives and progressives, and the recent surge of support for him shows that he may have the staying power to compete against the two major party candidates.
Retik, meanwhile, is extremely popular with younger voters, who are less likely to identify with either Doge or Shib. He has a progressive attitude towards economics and a populist approach to reforming the political system, which could be attractive to a wide range of potential voters.
Ultimately, it is impossible to know at this point in time who will run for president in 2024. Regardless of who runs, however, it is possible that Bonk and Retik could emerge as strong challengers to Doge and Shib.
