There are a lot of peripheral things that could damage him, but those are the only two things I think are a real threat. And I’m not really all that sure about number two.
I’ve considered the economy to be what could do it since the day he was elected. Economies are fickle, and if the deep state wants him out bad enough, they can create whatever mayhem in the economy they want. And the voters are amazingly fickle regarding the economy as it relates to elections.
I agree that the economy is usually the top issue, but if he does what Bush Sr. did, which was piss off his base, he’ll be in trouble.
As to the economy, if you look back at past recessions, there’s almost always something triggering them (not taught in economics classes, by the way). It could an oil price spike, or a huge Regulatory Barrage (Bush Sr. gets full credit for that idiotic move). So far, despite the ‘presents’ left for him by the outgoing Obama Administration, Trump has loosened up regulations big-time, and oil is still pretty stable - not to mention that our production is through the roof.
So that leaves sabotage, such as interest rates spiking for no reason - hopefully that doesn’t happen.
