Democrats Believe That Democrats Are Fighting for Working People

Working class Republicans are told that Democrats are opening our borders, flooding the country with immigrants who are stealing American jobs and taking valuable goods and services from taxpayers. Then, when the immigrants get citizenship, they vote for Democrats, so as to get even more free things.
This plays into the narrative of voter fraud and strict criteria for voter registration, while it excuses gerrymandering.
I think virtually ever voter believes one way or the other, and very few of us are changing our minds.
