The article isn't really talking about Paul winning though so while that point is valid Bugeye, it's also irrelevant.
The article is saying that they think Paul's plan is to win enough delegates to see major policy changes in the Republican platform. Paul has been encouraging his constituants to stay late after voting and become delegates. Who knows, if Paul can insert enough of his swagger in the Republican's policy, you might actually see some of his voters back whoever wins the GOP.
