Well, this would be clear yes/no if there were stats of people being turned away at the border, or returned. But there are not as I suspect most are still in the US and in a number of days, they are released into the US. Trump blames the laws, Sessions sleeps, Americans lose. I am not very optimistic that catch-and-release is stopping, even less that the 10s of millions of illegal aliens will be deported.
BTW I like your tagline
No Amnesty! No Catch-and-Release! Just Say No to All Illegal Aliens! Arrest & Deport!
That is the answer to all of it is just say no.
The democrats want a permanent monopoly on power and with whites dying more than giving birth. With taking in 1.5 million new legal immigrants a year, plus illegals on top of that. the dems are getting their wish.
