Most reports say 1,500 FAMILIES, not 1,500 individuals. And growing as of the end of last week. Lots of incomplete and dated info. Wonder what it looks like tomorrow and where is their progress. This is an American-funded and coordinated invasion by Pueblos Sin Fronteras out of San Diego.
It is fair to conclude that the group organizing and sponsoring this caravan, Pueblo Sin Fronteras ("town without borders") has provoked a backlash. First of all, its name reveals too much: they want no borders, which means that potentially hundreds of millions of poor people who would like to move to the United States and take advantage of our generous welfare provisions could overwhelm our native population if they realize their goals. Open borders would benefit the Democratic Party, but until now, they have been afraid of openly advocating for them. Pueblo Sin Fronteras has put them in a difficult situation.
