I thought it was the voters that choose who got the nomination
we, as voters, choose delegates to the party conventions, who in turn select the nominees.
We do not directly nominate presidential candidates within the two major parties.
Just as we don’t vote directly for president in the general election, but are voting for electors to the electoral college, when we vote in presidential primaries, we are voting for delegates to the convention, who in turn nominate the candidates.
I know all that it was sarcasm
