The Republican Presidential Nominating Fight is not officially over yet, despite the numerous candidates who have dropped out of the race. While Donald Trump has been projected to win the nomination with a huge delegate lead, it is still possible that another candidate could mount a last-minute effort to overtake him. This would require an incredibly unlikely combination of events and circumstances to come together in the remaining primaries and caucuses of the nominating process.
In order for another candidate to overtake the current frontrunner, they would need to get a huge surge in support among voters in upcoming primaries and caucuses. This is due to the fact that Donald Trump currently has a major delegate lead. In order to pull ahead in the delegate count, the other candidates must secure a large majority of delegates in the remaining states. This is an enormous task due to the fact that the Republican Party allocates delegates by a proportional system. This means that even if the other candidates are able to win a state, they still will not necessarily earn the same number of delegates as Donald Trump.
The other factor that could potentially shift the momentum in the race would be if another candidate were to drop out and throw their support behind one of the other candidates. This could put the pressure on the other candidates to win additional delegates in order to ensure that they will become the nominee. However, as of yet there have been no indications that any of the other candidates are considering dropping out of the race.
The Republican Presidential Nominating Fight is still a long way from being over. Despite the current delegate lead held by Donald Trump, it is still possible that one of the other candidates could mount an effective last-minute push to overtake him. However, it would require an unlikely combination of events and circumstances for things to play out in such a way. For now, the candidates will continue to compete in the remaining states and the future of the Republican nomination is still in flux.
