The people of Virginia did not vote for these delegates in any form.
These Delegates become delegates by following the process.
They simply ttended their precinct meeting in their neighborhood. There is where they became delegates there to their county convention.
They attended their County Convention and became delegates to their State Convention, and from there they were elected by the other delegates in the room assigned to their district, at the State Convention. Those elected at State are the delegates to National Convention.
TRUMP supporters largely did not show up at their precinct meeting, or we would not be in this fix. The few TRUMP supporters who did show up throughout the process, were so outnumbered by other candidates (Cruz) we could not get nominated as a delegate, never mind elected, as a delegate to National Convention.
If they succeed in stealing the nomination from Trump I will NEVER vote Republican again.
