This is horse manure...
The person with the most delegates (if there is one) will be the nominee.
You would have so much turmoil in the streets of Cleveland if that was not the case.
This is garbage being pushed by the Trump campaign because there is a solid chance he is going to get his hat handed to him starting tomorrow night.
Do you honestly believe Trump will lose badly tomorrow?
To add: It is fair to say that a majority of Republicans did NOT vote for Trump. Also, the threats of protests will quiet down if Trump supports the nominee.
