Building the wall unilaterally may cost Trump a second term, IMHO. The entire media, including FoxNews will label him the biggest bigot in history. If he starts building the wall and loses his election, the wall won’t be finished.
With that kind of thinking, it will never get built.
2 things that had to be done to save the patient called America-—Build the fargin wall and drain the fargin swamp.
It’s looking more and more likely that neither of those 2 things will happen. Meaning the dems will RULE forever and the country will probably descend into all out gun play.
