Answer:
Democrat.
Step-by-step explanation:
Republicans are nore likely to view immigrants as threats (78% compared to 19%)
Republicans also have much stricter immigration policies, meaning immigrants would much rather go through the easy way with Democrats.
More Republicans want immigration to be illegal than Democrats.
Republicans(40%) think its okay to separate children from their parents when accused of illegally immigrating while only 10% of Democrats think thats okay.
So Democrats are just more lenient and understanding towards immigrants so states with more immigrants are likely to be democratic states
