That would certainly stun those South of the border...mass numbers of people headed there way...then they could deal with us as illegals for a change. I hope they have my freebies waiting and are ready and willing to cater to me.
Mexico and Central America are going to be overwhelmed with refugees from Canada and our northern states. Tens of millions of illegals will also be part of that mass migration.
The influx is going to change those countries forever. I expect political lines will be redrawn, worldwide.
