Can you expand on this?
It's unclear if you see value in the "traditional" and it's not clear how your political barometer is calibrated, as we're still center-right as a whole.
Maybe if the ACA had included single-payer I'd say we were starting to lean left, but given the pro-business stands from both major parties, I don't see how you arrive at anywhere left of center.
I say center-left because Obama has been very outspoken about:
1. Taxing the rich at higher rates.
2. Providing more government services to more people, including illegals.
3. The "flaw" in our Constitution lacking "positive" rights (what government MUST do FOR you rather than what it MAY NOT do TO you.)
4. Ending coal and cutting back oil in favor of solar and wind energy (and proper tire inflation.)
5. Amnesty for illegal aliens and an end to enforcement of existing immigration law.
6. Rewarding government service with school loan forgiveness (meaning paid for by everyone working outside of government.)
7. Moving things like health care regulation to the federal government.
8. More federal control of primary education.
9. Preventing voter ID.
10. Government "spreading the wealth around" (which requires government taking the wealth and giving it to someone else.)
11. The federal government spending much more money.
12. Gay marriage and gay rights in general.
13. Drawing down the military.
None of that is remotely conservative. Yet Obama won fairly strongly. Ergo, center left, if not just plain left.
