Donald Trump had a big night Tuesday night. But he had an even bigger night with delegates because of the GOP delegate rules.
Winning an impressive 57% of all the votes cast, he received 95% of the delegates. That's because 4 of the 5 states had either "winner-take-all" or "winner-take-most" primaries. The GOP delegate rules are favoring Trump.
Despite all the complaints, the GOP delegate rules initially favor the Trump campaign, so far giving him 90 more delegates than he earned from the popular vote. That might be enough to win the nomination, putting him over the 1,237 magic number needed to win outright.
How has this discrepancy impacted the other candidates so far? Ted Cruz has a bonus of 109 more delegates, while Kasich has 89 fewer and the other candidates who have since dropped out have 110 fewer. But they don't matter if Trump wins on the first ballot.
The AllSides analysis shows the difference between the number of delegates awarded per state and the number of delegates that would have been awarded if determined purely by popular vote. Several states ignore the margin of victory and award all or most of their delegates to the victor. Trump won all the delegates awarded so far in 4 of the 5 states, with only Rhode Island allocating delegates based on the percentage of the popular vote.
Previous to Tuesday's primaries, Donald Trump had 53 more delegates than he would have earned from a pure "one-person, one-vote" system, moving him closer to the majority he needs to win the nomination on the first ballot at the Republican convention. Ted Cruz has earned even more delegates beyond the popular vote, but they only come into play if Trump fails to win the nomination outright on the first ballot.
