Fiend God
Let me rephrase:
Because they are the largest single voting bloc, you have to at least appear to take their concerns seriously, not just vilify them.
For instance immigration: This is a serious concern if you are a non-college-educated white male. It's not racist to think someone who isn't an American might illegally cross the border and do your job for less money.
It might not be racist but it's silly. If you want big salaries, expect other people to be willing to do the same job for less.
