So you are in favor of surrendering the country to illegal aliens?
And building a 1900 mile wall across the southern border? Is he out of his mind? How much would that cost? How long would it take? How would it work - illegals would climb over it, or burrow under it, or just simply go round it or over it. How are you going to police such a wall? How much manpower would it take? Fixed walls dont stop invasions. Hadrians wall didnt. The great wall of China didnt. The Maginot line didnt. It sounds tough and appealing to conservatives, but its utterly impractical. He must know that. If he doesnt, theres no way he should be president.
