Kasich would've gotten 45-49% of the latino vote. Dubya got 44% in 2004, and he's much more divisive and conservative than Kasich is.
A Kasich-Rubio or Kasich-Martinez ticket would have CRUSHED Hillary in the biggest GOP victory since HW Bush in 1988. They would have won 400+ electoral votes and the popular vote by around 10-12 points.
This is a 408-130 win:
I really doubt anyone not an incumbent could manage that.
From looking at that map, HI, IL, NJ, CT, are probably stretches, but everything else would have been within grasp. So yeah, I exaggerated with 400+; it would've been more like 370-385ish.
