government should not be intervening in a woman's personal medical decision
How can you say that a medical decision is personal if she cannot pay for it? I would agree, that your body is inviolate so long as you pay for its upkeep, but once you start waving the cup around for someone else's dough to take care of you, the placer of the coin in the cup has more say than you.
You're conflating the thread (public health care) with the specific point there (access to abortion clinics). Abortion clinics exist in the places where they have not been forced out because they meet a demand that exists today and doctors can make a living at them, even under today's health care system. Democrats generally (though not monolithically) assert that a woman who needs an abortion should be able to get one without interference from the government. This principle is able to stand on its own, regardless of payment. A separate common Democratic assertion is that anyone's access to medical services should be a given, not only because of the moral position but also because of the aggregate reduced cost of making preventive care available to people who would otherwise try to wait and hope it goes away on its own and end up with expensive, serious conditions. These are separate principles.
As for free trade, we are again mostly in opposition. Isolationism is, economically speaking, a terrible idea. Environmental, financial and labor issues certainly need to be more prominently considered in trade treaties, but shutting out imports would be devastating to the US economy. We already have a manufacturing base; the largest one in the world by a wide margin, in fact. The US is better able to take advantage of an interconnected world than any other entity on the planet partly because of that manufacturing base, which can import raw materials and export (or produce for domestic consumption) higher-valued goods. Buying American is nice, but we just don't produce everything we consume anymore because it's not economically efficient for many lower-valued goods.
I'd be interested to see your basis for relating marriage and abortion rates to trade; there doesn't appear to be much correlation between rich areas of the country and areas with higher marriage rates, for example.
The problem with a state run insurance plan is that that the state has never made anything more efficient. Ever.
Yeah! Retirement savings were so much more efficient before Social Security! Sure, it meant lots of old people ended up begging on the streets, but those people didn't have any money by then, so they didn't count against the efficiency!
