It looks like radical conservatives, who hate government, can't govern. The Speaker of House debacle points that out. Hardliners are holding out against McCarthy, who is quite conservative himself.
The center does seem to be strengthening in USA. There is some speculation that Democrats, in the House who are now staying out of the internal Republican strife, may weigh in to push the situation, in the Republican majority House, more to the center.
A more moderate Republican, Fred Upton, is a possibility, though retired. He could come back to fill that position and at least get the House functioning again.
As for more radical Democrats, I find myself, politically, pretty moderate. In personal lifestyle, I am quite outside the norm of American life. No car, no family, except brothers and sisters who I get along with okay. I seem to have less interest in money than most Americans.
Still, it seems like the politics of the far left isn't supported by the lifestyles and asperations of most Americans so moderates, making incremental changes, seem to be the most viable political option.
As for addressing climate change, that is a global problem and we may just have to learn the hard way. Climate is going to follow the laws of physics, whether politicians, and the public like it or not.
Much is still unknown as to just how that will play out in our complex world and economy. It looks like our best hope for a technological solution to the climate change problem is solar energy.
