Well, Abbott is doing it to fire up conservatives and make a national name for himself, but if the immigrants are agreeing to get on the bus to NYC, then I really don't have a problem with it. If they are getting bussed away against their will when they actually have family in Texas, then that is completely different.
The Florida thing is a whole lot worse because I really doubt these immigrants are agreeing to get flown to Martha's Vineyard, where they don't even have transportation to their required court appearances.
