Of course Trump can rewrite the electoral map. He'll have the enthusiasm factor on his side. Besides that, inroads into minority communities (including Muslim) will be significant. Why? Groups that still respect family-based culture look up to the Alpha Male who provides strength and determination. hillary is weak in all those areas in which that strength and wisdom is highly regarded.
JMHO
This is nuts. Trump, and any Republican, loses minorities big time. This time Republicans will lose more on the Hispanic vote than in other years. Whites are the only place to expand.
