Despite his complaints, the GOP's delegate system has given Trump a 22-point bonus

Trump now leads the Republican field with 756 delegates — or 45 percent of all delegates awarded to date. Yet he has won about 37 percent of all votes in the primaries, according to the NBC analysis, meaning Trump’s delegate support is greater than his actual support from voters.

For each percentage point of total primary votes that Trump has won, he has been awarded 1.22 percent of the total delegates.

In other words, as a matter of Republican Party math, Trump has been awarded a delegate bonus of 22 percent above his raw support from voters.

By contrast, Cruz has been awarded about 1.14 percent of the delegates for each percentage point of votes he has won — a delegate bonus of 14 percent above his raw support.
