Voters in five states will have their say in the Republican presidential primary process Tuesday. Combined, 14 percent of the delegates required to clinch the GOP nomination will be up for grabs. Even if he won all of Tuesday’s delegates, Donald Trump still wouldn’t have enough delegates to clinch the GOP nomination.

In some states, the rules are simple. In Delaware, for example, whoever gets the most votes gets all the delegates. Other states are more complicated. In states that give each congressional district three delegates, it’s more like several small primaries than one statewide vote.
