If Trump won 1/3 of Hispanic votes, then that alone isn’t the issue. Here in NJ there is mass trafficking of Asians as well, and many of them are Dems. In the end, it is white females and soyboys who deliver the Dem victories; these non-whites are still not much of the voters (here in the northeast).
If you’re only winning 1/3 of the major growing faction in this country, you’ll be a minority party forever before long. The whites are the main problem though, especially females.
