What nonsense. You have exactly the vote written on the ballot. People elect representatives who vote on their behalf on matters of national importance. That is true for Senators, congresspeople, and electors of the electoral college which are the three elected federal executive offices. Primaries are to decide amongst like minded voters who they want to stand but no one is barred from standing due to a primary.
The whole idea of voting for someone to vote for someone on your behalf is stupid and unnecessary. The electoral college system and the district voting system are designed to allow gerrymandering and other unfair practices that all together result in the very obvious fact that 1 vote != 1 vote.
