All the blue cities are saying they won’t allow it. The whole illegal topic really is about voting and nothing more.
If we don’t deport. They will continue to flood the country with migrants who will vote for them.
So I am not sure how Trump is going to deport in blue cities. Which is were the deportations need to take place.
A nice marketing program, like: "Come Home for Christmas" in all the appropriate languages (along with other seasonally themed campaigns) may be a nice way to get the ball rolling.
