I’m certain that for each caucus, each campaign who was competing sent found someone from the region who was promised transportation to the convention.
However, the caucus didn’t have to choose from the delegate nominees the candidates had prepared, anybody who showed up could run to be the delegate.
Of course, it would make no sense to run for delegate if you couldn’t go.
So unless you think Fred Thompson couldn’t find 12 people who would be his official delegate candidate for the 12 real caucuses, the suggestion is rather meaningless.
I just reiterated what the article stated. Take issue with the reporter, not the messenger.
