It’s a long, long way out, but I’ve said for six months that any Republican not named Bush would be Hillary. If it’s Trump, it could very well be a landslide electorallly, although the popular vote is a lot tougher now with the two big lib states, NY and CA, putting millions of votes in the D column.
I can’t speak to California, but I believe that Trump would very likely carry New York and New Jersey as well. The northeast likes him and sees him as “one of their own”.
