Not at all! And, frankly, people who claim it can't be done are just afraid to try.
And the Democrats and interest groups will try to block it. Already, many of these groups are comparing mass deportation to the Nazis and the rounding up of the Jews for the Holocaust.
Let them do it. Deportation must be included in any program that purports to enforce the law.
Deportation is part of attrition thru enforcement. Mass deportation is not feasible and it is politically impossible. No politician supports mass deportation including Jeff Sessions and Steve King.
