The delusion of illusion is so thick they accepting bizarre funding proposals like corporate sponsorship ("this mile of wall is brought to you by Coca-Cola"), have drug smugglers pay for it (like their money isn't stashed away safely), or just pretend that Mexico will magically pay for it eventually.
Somewhere in there Trumpists know it is all fake but they want to believe so badly that they do believe and in believing they have to declare any hint of truth as "fake" lest it shake their beliefs.
