Won’t that leave a gap at the bottom?
LOL!
Ordinarily, yes, but in this case, the rate of "manure" emanating from the White House at the present time, and landing on the White House lawn, far exceeds the rate of the raising of the fence, so there is no gap, just a very rotten smell.
I suggest some razor wire for that ghetto and prison chic. At least until 0 leaves the white hut.
