to be clear, a lot of deportations have been taking place regularly since Reagan. The full scale roundup will take awhile because the locals will hide their friends and family members. Even Obama was deporting people. But then the border was even more porous and they would just go down a few miles and walk back over. It's possible we will never know how many have come across as many are repeat offenders. One illegal I spoke with at Home Depot told me he regularly walks back over to go see family and deliver money. Then he comes back in. This was during the height of Obama years, but to many of them, it's a game.
