Much to the dismay of some Republicans, the party’s primary process is working just as intended. Designed to choose a nominee quickly, this year’s rules have advanced that air of inevitability forming around Donald Trump, who has won 15 of the first 24 contests.
More votes means even more delegates
Top-performing candidates get more delegates than their vote totals might suggest. Trump won about 35 percent of all the votes cast through March 8 but earned 43 percent of the delegates available in those contests. Ted Cruz, who won six states in that time period, also benefited a bit from rules that help the leading candidates.

This delegate boost will grow come March 15, when most states have rules that favor the front-runner.
Leaving it up to the states
The Republican National Committee gives states and their parties leeway to decide their process within some boundaries, resulting in a patchwork of rules.

WINNER-TAKE-MORE
These states reward winners heavily.
In some, the winner in each congressional district earns all three
of that district’s delegates. In South Carolina, Trump won statewide delegates and every district, turning
it into a winner-take-all state.

How many delegates are available in each type
Only one-quarter of the delegates are given out in strictly proportional states. Another quarter come from proportional states that become winner-take-all if a candidate crosses a certain threshold, which varies by state.

How the schedule has changed
In the last several cycles, many states had moved their contests earlier, forcing the primary calendar into January as they jockeyed for influential first-state status. This made for a long primary season. Trying to reverse this trend, the RNC established penalties in 2012, but some states, including Florida, moved their contests up anyway.
This year’s delegate penalties are much more strict. The party banned January contests and allowed only four states to vote in February. It also moved the last primary earlier, shortening the cycle so a nominee would more quickly emerge from the field and be better positioned for the general election.
The party also halved the time frame in which states are required to distribute delegates proportionally, which spans March 1 to 14 this year, compared with all of March in 2012.
For this reason, contests from March 15 on become far more consequential, and far more favorable to the front-runner. Trump can lock up the nomination by winning these.

While Trump stands to benefit from these state rules, they could end up being his undoing. His opponents are looking to the delegate-rich winner-take-all states such as Florida and Ohio to quickly close Trump’s lead. While unlikely, if someone can seize the front-runner status from Trump, the rules would work in their favor instead.
