Are there enough whites in the US to elect a republican president? Whites are now 60 percent of the US population. It was around 80 percent when Ronald Reagan was elected. Trump may attract many white republican/conservative non voters; i.e., whites who haven't voted in 40 years, as well as independents who think they're above politics and never vote. Can Cruz bring these voters to the polling places in big numbers? If he can't, he will lose and Huma Abedin Weiner will be running the White House.
