Not if he’d still lost the nomination. If he had won the nomination though I think she would have won. He had zero of the crossover appeal that Trump did and would have done poorly with both suburbanites and the white working class. She definitely would have held the blue wall and possibly won PA by a wider margin then Obama had either time.
Wasn't his path to a delagate majority already mathematically eliminated after NY primary? So even before the IN primary in early May.
So very doubtful, imho, Trump would still have won the nomination outright. Even if the RNC was kind of a mess, I doubt that would have changed much since he already seemed DOA in the summer.
