A functioning legislator discusses these nuances, and comes up with a legislation that enacts the policy such that most people can benefit from it. This is one of the benefits of having a diverse ruling class. No one person needs to know how a popular policy gets enacted, that is the purpose of representative democracy.
You're technically inaccurate because 58-60% is not an "overwhelming majority".
I'm not a US citizen (or resident), and I find it almost unbelievable and absolutely unacceptable that you don't have some form of universal healthcare, for example. I probably agree with you politically way more than I disagree with you, but the other posters points against you still stand.
EDIT: I realise my first paragraph here might sound a bit harsh, that was not my intention - my intention was to make it explicitly known to you such that you might take it to heart and it might possibly be helpful to you to realise.
The same applies to solving global warming. Carbon taxation was actually a feasible solution with conservative support. Now instead, a huge chunk of the liberal position has shifted to the green new deal, which is a jobs program and wealth redistribution scheme only orthogonally related to slowing global warming. Nuclear is another viable solution to global warming that nobody wants to touch because science is scary.
I personally want carbon tax and police abolition, but there is no consensus on either of these, and what I personally want doesn’t matter. I am not a dictator and the USA is not a dictatorship. It is the legislator’s job to gather what the people want, and find a way to deliver it in a way that will benefit the most. However the American ruling class is not even pretending to be interested in what policies the general population supports.
None of those things are supported by an overwhelming majority unless 3/5ths now constitutes “overwhelming”. Additionally, your view of what the issues are show how biased your approach is to begin with.
- Almost nobody has an issue with reducing police violence, but a bunch of people have issues with getting rid of the police.
- Almost nobody “wants foreign wars” but a bunch of people think military intervention is needed.
- Nobody is against taxing the rich, it’s already right in the tax code and the top 1 percent pays something like a third of all tax revenues already. What a bunch of people are against is arbitrarily raising their taxes further because of tall poppy syndrome.
- Reduce carbon emissions. Yes, but sadly not overwhelming majority still and even then, the “how” is critical and there is even less common ground there.
