Biden's resignation unleashes a new political era in the U.S. How will it affect Harris and the Republican Party? Uncertainty grows ahead of the Democratic National Convention in Chicago. What will the political future hold for us?

President Joe Biden has shaken up the American political scene by resigning from his candidacy for the presidency with the Democratic Party, an announcement that has triggered a series of unexpected and significant consequences. Biden's decision to endorse his vice president, Kamala Harris, as his successor in the Democratic candidacy has generated a great momentum for Harris, who is now at the center of political attention. Biden praised Harris, stating that choosing her as vice president was one of the best decisions he made in his life. This endorsement has led many Democrats to seriously consider supporting Harris as a presidential candidate, especially given her position in the constitutional line of succession and the funds raised so far for the campaign. However, Harris' choice is not without risks. Polls show that her approval ratings are not significantly better than Biden's, and her record as vice president has been criticized in some areas, such as her handling of the migration crisis at the Mexico border. Furthermore, Harris has already attempted to run for the presidency in 2020 unsuccessfully, raising doubts about her ability to unite the party and win the presidential nomination. Despite these challenges, the option of Harris represents one of the few alternatives for Democrats at this crucial moment. The Democratic National Convention to be held in August in Chicago is shaping up to be a highly interesting and unpredictable political event, where Harris' figure will be at the center of attention. The possibility of an internal dispute among several candidates for the presidential nomination adds a dramatic element to the convention, which could turn into a "every man for himself" scenario rather than a display of unity. On the other hand, Biden's resignation has left the Republican Party bewildered, as they had focused their campaign strategy on attacking the supposed weaknesses of the Democratic president. Now, Republicans are forced to rethink their strategy and adapt to a new political landscape in which Harris' figure could play a prominent role. Republicans are likely to try to associate Harris with the alleged failures of the current administration and portray her as a candidate of the "radical left," in an attempt to discredit her candidacy. However, the strategies used against Biden may not be as effective against Harris or other potential younger Democratic candidates. In conclusion, Biden's resignation has triggered a series of unexpected events that have shaken the American political landscape and created uncertainty in both parties. With the presidential race becoming increasingly unpredictable, the coming months promise to be intense and full of surprises for American voters.
