The president is nominated by the members of a political party, either by voting in primary election or at the national convention. In the case of primaries, the voters do not actually have to be official dues-paying party members-- they merely have to declare that they support the party whose ballot they ask for.
His role is to be nominated. He stays out of sight until it is time for him to give his speech at the end of the convention. Behind the Scenes he is meeting with power brokers, people who may be his VP, and getting his organization in line for the election.
The political parties nominate their candidates.
Each party's Presidential nominee (or incumbent) selects a running mate for an election. If a Vice President leaves office, the sitting President can nominate a replacement to be confirmed by the Congress.
