Pat Buchannan is a liar and propaganda machine. Ted Cruz did not pouch delegates that were entitle to Trump. He won at large delegates and Rubio delegates, that under Louisiana State LAW, became available when he suspended his campaign.
What Cruz did was to get loyalist elected as delegates but are still legally bound to vote for Trump and only become unbound under each STATE LAW!
However, I admit that at some point they can be unbound and can vote for Cruz but this is not stealing. Even Pat admits that Trump must convince at Large or Rubio or Kasich delegates to vote for him- is this stealing? Even worse, Pat is arguing to convince these delegates on the first ballot which is totally stealing and unlawful.
Maybe what Rafael is doing is "within the rules," but the average primary voter neither understands nor cares about delegates or their appropriation. All they care about is that their vote is being cancelled out by back-room, machine politics.
The bottom line is that Trump generally wins when voters decide. Cruz always wins when voters are removed and his fellow GOP establishment insider hacks decide.
