Cape May - Why are the democrats suddenly interested in the unbelievable amount of migrants in the last three years. Could it be because it is an election year. They have been poring over the border and President Biden, VP Harris, and Homeland Security Mayorkas did not care and there were very few visits. The President and VP made more visits to Pennsylvania than the Southern border. If the Texas Governor didn’t share the wealth of illegal immigrants to other cities, I doubt if there would be any concern.
