I would suggest that the disease, in this case, is lack of voter ID, not legal or illegal immigration.
Proper vetting of voters at the polling place make immigration irrelevant to the political process.
Right now we take in a million and half legal immigrants per year. Most from Mexico and South America. these voters vote 70% democrat. Even if we eliminated all illegal immigration, in the 20 years or less the democrats will still have enough voters for full control of the country.

Not entirely true. Since illegals are counted in the census they affect the number of reps in Congress and how many electoral votes are given. Since states with lots of illegals and/ or legal immigrants tend to turn blue it also affects their local politics.
