Unexpected turn: Biden resigns and Harris emerges as a potential presidential candidate.

The American political world has been shaken by the news of President Joe Biden's withdrawal from the electoral race, who finally succumbed to pressure and decided not to run for the presidency under the Democratic Party. This decision has left an uncertain scenario for Kamala Harris, the Democrats, and the Republican candidate, former President Donald Trump. Biden's resignation has caused an unexpected turn in the presidential race, opening up the possibility for Kamala Harris to be the Democratic candidate for the presidency. The full support that the outgoing president has given to Harris has boosted her position as a potential successor, garnering support among Democrats seeking to avoid further uncertainty at a critical moment. While Harris has the backing of Biden and access to the funds raised so far for the campaign, she also faces significant challenges. Polls show that her approval ratings are low and she may encounter difficulties in a face-off with Donald Trump, who remains a polarizing figure in American politics. Furthermore, Harris's experience as vice president has had its ups and downs, especially on issues such as the migrant crisis at the Mexico border and abortion rights. Her previous attempt at the presidential candidacy in 2020 also raised doubts about her ability to lead a successful campaign. For the Democrats, Harris's candidacy represents a risk, but in a context of lack of secure options and the threat of a possible Trump victory, the party faces difficult and crucial decisions for its future. The Democratic National Convention in Chicago promises to be an unpredictable event, where party unity and the strategy to follow are at stake. On the other hand, Biden's withdrawal has disrupted the plans of the Republican Party led by Trump, who focused his campaign strategy on attacking the alleged weaknesses of the Democratic president. Now, Republicans must adjust their focus and strategies to face a new Democratic candidacy, possibly led by Harris or another younger candidate. With the American political landscape constantly evolving and the elections drawing closer, both Democrats and Republicans find themselves in uncertain and challenging terrain. The coming weeks will be decisive in defining the course of the presidential campaign and the political future of the United States.
