Ok, this is reasonable. There have been some indications that Trump might be softening on the issue. Language alluding to this policy was removed from his campaign website on election night, for instance, and it hasn't really come up since (at least from him). I'm still very concerned that it was said at all, but you can certainly make an argument that this statement doesn't represent the current state of things.
> well then why is Obama so highly regarded by the left?
You have veered into defensive tribalism. We are not discussing in what regard Trump is held, but rather the likelihood of him implementing a particular policy based on what he has said about it. Whether or not liberals forgave Obama's transgressions is irrelevant to a muslim registry.
