Kellyanne Conway wants to get suburbanites who don’t want to vote for a racist, especially women, to come home. They’ve figured out that Trump’s mass deportation stance is an impediment to that (something tons of polling confirms). But Trump is so identified with a hard line on the issue with his base, he (with her guidance) is trying to shed the mass deportation label (unpopular) with an approach that emphasizes enforcing current law, protecting wages of Americans and doing it in an undefined “fair and humane” way.
He’s trying to make us believe he’s changing his policies when in fact it’s an attempt to have it both ways. He’s telling the base, “I might not be saying anything about mass deportations and deportation forces, but don’t worry, it will amount to the same hard-edged approach.” But he’s telling suburban voters, “I’m not talking about mass deportation and deportation forces, I’m talking about the normal application of law and removing people who have broken the law, with an initial emphasis on bad guys, just like Bush and Obama did. And if those removed want to come in legally all they have to do is apply once they’ve left the country.” (That sounds reasonable to the uninformed but means in real life that they will never be able to come back.)
This is a PR strategy to de-radicalize his mass deportation policy without changing the policy itself.
