In the Louisiana primary, Trump got 41% and Cruz got 38%, so Trump won by about 3%. Louisiana has 46 delegates, so that works out to about 1 delegate for every 2.2% of the vote. In a perfect world, that means Trump should probably have gotten 1 more delegate than Trump. It sounds like it turned out even because of some rounding/thresholds that were agreed upon in the rules. One delegate doesn’t sound like that big of a deal to me.
What I think is a big deal is who the actual delegates are. Are they Trump supporters chosen from a slate that was named by the Trump campaign? Or are they local party officials, who are pledged to vote for Trump on the first ballot, but are not necessarily committed Trump supporters? If no one wins the first ballot, it will make a huge difference on how the convention goes.
It’s the winner/loser thing with Trump I imagine. If they both get the same number of delegates, how is Trump the winner?
