“New York is as much in play for Trump as Texas is for Clinton.”
Difference is Tump is from NY.
It won't make a difference. Trump is not going to carry New York and Clinton is not going to carry Texas. If Trump can carry Nevada, Colorado, North Carolina, Florida and Ohio then he is president and he doesn't need New York. All of those are far more winnable than New York ever could be so he would be well served to concentrate there.
