These are terrible poll questions.
For example,
5. Should the US invest more (this means gov spending) in critical infrastructure and apply more regulations (to prevent things like train derailments) or less?
This is really two questions.
What constitutes "critical infrastructure"? Does that include the military? Roads? Bridges? And how do we pay for that? It's easy to say "yes, we should invest in infrastructure" (whatever that means), but hard to justify, say, cutting funding for schools or law enforcement or whatever to pay for it.
As for the second part, is there any evidence that "more regulations" prevent train derailments? Certainly, there are places where regulations do that, and there are other places where they just make life difficult and increase costs for everyone, while providing no benefit. Regulations have a cost, too. Would I pay an extra $.01 on train tickets to measurably reduce derailments? Sure. Would I pay an extra $100 per train ticket to do nothing? No. The question is too vague.
An honest response to this question from an intelligent person would be "no opinion" because the question is too broad and too vague for anyone to have a valid opinion on it.
