Agreed. Mika may as well have said "He looka lika man" and a bunch of disingenuous people would have run with that one too.
Those were not socialist views. They were simply remarks from Mika and not policy. Being an outsider is not socialist, nor is attracting thousands to your rallies, or in favor of every one having access to healthcare (almost every one agrees with that. You could say that Sanders favors capitalism rather than Trump favors socialism. Both assumptions are wrong and the question by Mika was silly and proved absolutely nothing about Trumps policy positions.
Of course that is not what was said about healthcare. The word she used was Universal Healthcare (commonly known as single payer). Not everyone have access to healthcare. Nice try though.
