Who is getting tired of what, may have more to do with African Americans getting tired of Democrats pushing them under the bus to chase foreign nationals. If you capture and maintain the vote of a demographic by instilling in them you are there serve them, when you turn your back on them and start courting the competition, don't be surprised when they tell you to take a long walk on a short pier.
Lol
I know, it is funny. African Americans may have been used and abused, but they aren't as stupid as some would think. If Democrats are more interested in running to the border and kissing babies of illegal immigrants for political gain, a young African American on the corner in Baltimore is going to wonder why Democrats think it okay to excuse illegal activity and "get theirs", while he cannot engage in illegal activity and "get his".
You don't even have to be talking about whether either is really right and wrong, for the young African American to understand he is getting screwed (it's obvious to him).
