Trump was elected because he said he would stop the flow of wetbacks and would build the wall. Two years into his presidency and he has accomplished neither. We've actually got more wets coming in than ever.
His "agenda" was his anti illegal platform. He has not accomplished his agenda. You can easily find any number of threads with many FR posts complaining about it.
The reason why is irrelevant. The point is that his agenda has not been successful.
DUDE! You have tunnel vision. Trump was elected on "Make America Great Again!" and building the wall and immigration control was only a small portion of that, not the "be-all-and-end-all" of his campaign. Candidate Trump made over 200 campaign promises all of which, including the Wall and immigration, are being moved forward, and YOU focus on just the most difficult to accomplish due to obstructionist action I outlined. Trump is good, but he cannot act outside the law, like a dictator, that YOU want. The wall IS being built and illegals ARE being turned away.
