As for "temporary," that's an obvious lie by the administration. They claimed that it was a temporary thing to keep the country safe while they reviewed how people from those countries are vetted. The original ban would have expired by now, so they've had enough time to review their vetting process according to their own metrics, but the administration is still fighting for it in court. Why would they do that unless it was intended to be perpetually renewed?
As far as the ACA goes, the "skinny repeal" that failed in the Senate yesterday by a single vote was definitely not Obamacare-lite. It would have basically torched the entire medical insurance system by retaining the protections for pre-existing conditions while removing the individual mandate and not replacing it with any other incentive to maintain coverage while healthy. That's rather extreme.
On Paris, if climate scientists think the agreement is a joke (and that is, as far as I can tell, not at all true), then the fact that the administration withdrew from it surely demonstrates that they are quite extreme.
