Several reasons. Nonexhaustively:

- There's a large contingent of people who just do not accept that even though Trump is the president, he does not actually have a genius master plan. Not all of these people even voted for him.

- There are plenty of people who genuinely believe that significant protectionist tariffs are good policy.

- Lots of people who have voted red all their lives simply support and believe whatever Their Side says and does.

- The major mainstream media publications are all owned by extremely wealthy people, who a) have a vested interest in ensuring that the Republicans stay in power, so they can continue to push for more and more and more and more tax cuts (for themselves), and b) are very scared right now that they will personally be targeted by Trump if their publications speak against him.

And, of course:

- Plain old wishful thinking.
