The thing about Spicer is that while still coming across like a massive c*nt he has something clumsy about him that makes him kind of "likeable" or at least bearable. It's when he goes to the podium and tries to read his statement and gets about a million words wrong or starts stuttering, because he gets stuff mixed up. The same happens when he's trying to answer questions. You can clearly see that at times he just has no clue what he's talking about. He still acts as a twat though, but you kind of don't buy his "tough guy"-stick. With that Miller guy it's completely different. He really is like a Hitler Youth guy...
If I were to hazard a guess, I'd say Spicer's approach comes from the fact he
knows it's bullshit and doesn't believe it himself. Ever seen those people who lie, then have to tell more lies to cover up their previous lies, then can't quite remember how they told the initial lie? That's Spicer. Maybe his anger is borne from frustration.
A guy like Miller, well he doesn't have to believe anything. I don't know if he's quite at the point of "Trump said it therefore it is true" in his heart, but he's clearly much better than Spicer at dancing around and covering his lies.
Somebody really needs to challenge this along the lines of, "Look, the President has been claiming voter fraud for
months and you
claim to have evidence. But so far you have flat refused to release that evidence to anybody. Unsubstantiated allegations of such a grave matter are, at best, misleading; at worst, they're outright lies. Why are you lying to us? Why is the
President lying to us?? The American people aren't idiots. You're lying, Mister Miller. You have no evidence. There is no voter fraud. Stop. Lying."
