Trump still has plenty of support from large swathes of Americans despite his increasingly more overt actions.

For many, he _is_ doing what he was elected to do. This _is_ what the American voter wants. The American voter wants illegal immigrants out, does not care how it happens. They also want cheap oil and are willing to overlook the implications of international military action if it means they get it. They also don't care about the environment enough to curb their consumption or invest in alternative energy sources.

These preferences are all aligned with Trump's actions.
