That's absurd, neocons may be trying to harness the grassroots power of certain far right groups but their ideology is nearly identical to the ideology of say, the Clintons or Obama.
>"Muslim" Travel ban
Its a blanket policy on ALL travelers from a specific list drafted by Obama for a similar policy he too actually enacted. Muslims were not banned from say, the UK or Pakistan. It is also temporary. Even center leaning right-wingers have concerns about foreigners from unstable nations.
>Attempting to repeal the ACA
TrumpCare is almost Obamacare-lite, doesn't completely overhaul it, barely right-of-center, and to the more libertarian right-wingers, actually still a very liberal policy.
>Cracking down on illegal immigration
A solidly right-wing position, not an "extreme" one.
>Pulling out of the Paris climate agreement
Climate scientists think the Paris agreement is a joke, if we're basing your judgement of this on effectiveness towards combating climate change, even liberal politicians are guilty of being "extreme right" on this one.
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.
