“Even if Trump reaches the magic number of 1,237 the media and RNC are touting, that does not mean Trump is automatically the nominee,” Haugland said. “The votes earned during the primary process are only estimates and are not legal convention votes. The only official votes to nominate a candidate are those that are cast from the convention floor.”
Haugland explained the primary number is really an estimate. That’s because the eligibility of some delegates in how they are voted in could be questioned and their status may not be considered valid, Haugland said.
“Remember every state has a different delegate allocation process,” he said. “Delegates are picked up in state contests that can be winner take all, open primaries, and remember there are seven states that allow the candidates to pick their own delegates. Until those delegate challenges are settled, there is no 1,237.”
