I think its a perfect time and has been for a while to crack down. I certainly hope president Trump has a plan and knows what he doing because we about ready to see voter fraud as intense as ever - the leftist thought they had it with Obama then Clinton. The illegals are one thing to the democrats, votes.
It’s still a long time before the real Election Season begins.
You never know, someone from the republican party may be able to offer a serious choice to Mr. Trump.
Due to numerous ‘stop & go & stop’ incidents as you just described, I no longer consider a serious republican challenger out of the question.
I’m not talking about #NeverTrumpers; someone like David French or “Egg McMuffin”, neither of whom has much appeal or charisma. It could be someone relatively unknown out of their district. Someone who is in agreement with many if not most of the president’s policies. If nothing else, having a credible republican openly challenge him for the nomination, may inspire the president to become a little more organized in making things happen as he said they would.
