That isn’t true, but illegals don’t vote anyway so that isn’t what made the California electorate become a solid blue state. Texas has about the same percentage of illegals as California.
Look at how the vote breaks down and look at more than a 100 years of American elections, Catholics vote democrat just as they did in 2008, and California is almost a third Catholic today.
Look at the voting results in post 117. Protestants vote republican and pro-life in California, Catholics don’t.
I have made my point but you clearly are not understanding it.
