I will bet every penny to my name he doesn’t get in that range.
Hell, if he gets 20% they’re already in trouble.
Now add in his percentages of support among “hispanics”. He got about 28% among Hispanics in 2016 which was about the same percentage Romney got. His approval rating among hispanics is around 50%. Let’s say he only gets 40% of the hispanic vote.
Add just those two together and the Democrats are in big trouble. That would be a substantial improvement among both.
