Democrats begin process of officially making Harris their nominee
The process of officially nominating a political candidate involves several key steps. Typically, it begins with the candidate announcing their intention to run for office. Then, the candidate's campaign will work to gain support within the party, often through a series of debates and public appearances.
Once the primary election season begins, party members will vote in primaries or caucuses in each state. The results of these elections determine the number of delegates each candidate receives. At the party's national convention, these delegates formally vote to nominate the candidate.
If the process you mentioned is regarding Kamala Harris, it seems this might be a hypothetical scenario as currently Harris is the Vice President of United States nominated by the Democratic party and there is no official statement or process underway for her to be their presidential nominee. However, if such a event was to occur, it would follow the previously mentioned steps.
