>He again suggested this week that the US could refinance it's debt like a mortgage.

This reads as dumbing down the explanation of interest rates enough for the american population to understand or in other words

>>he does or says is filtered for his base and/or for self-preservation.

Per my comment, it could be but I haven't seen a shred of evidence that that's true. There isn't, in fact, any way to refinance the national debt or anything analogous to refinancing debt. In the past he's suggested we could default on some debt the way he has with his myriad failed businesses, but that would be an obvious disaster. I have never seen any public or private statements that indicate he has any understanding whatsoever beyond his nonsensical public statements. The only stuff we've seen leaked show the exact same levels of ignorance. His official actions all support the theory that he is truly an ignorant moron.

Show me any evidence to the contrary.

The “wall”. The money was only partially needed for building physical wall. The rest was electronic surveillance and deterrence. But dumbed down to the people as “the wall”. It’s been his M.O. his whole presidency

Show me any evidence. Public statements, rumors, anything that says Trump actually meant surveillance or deterrence. Because there is heaps of statements of him talking about walls meaning walls. Walls that are high and strong and can't be tunneled under or cut through. And his attempts to seize land to build on. And his leaked phone call begging President Nieto to pay for it like he said would literally happen (https://www.univision.com/univision-news/politics/transcript...) exactly the way he described it to voters. Show me anywhere that he acknowledges what percentage of illegal immigrants actually run across the desert versus using a legal border crossing. Find me any leaked statements that show anything more than the exact same facile explanations he uses in public. All I see are the same statements with more cursing.
