Don't know how that "it" crept in there. That remark should have read:

but except for the extreme influence of insurance dollars on all campaigns, I can't figure why politicians would even factor "insurance" (legalized gambling for investors) into universal health care. "Health care" and "health insurance" are diametrically opposed issues, as far as I can tell.

I'll add that the idea that companies would charge millions of individuals billions of dollars a year, the companies gambling that people won't get sick, the individuals gambling that if they get sick the insurance will cover their treatment, is a damned barbaric way of taking care of people's health. Because we all know who wins in the end in that formula.
