I think so. Trump fears Bernie. How many times has Bernie called Trump an outright liar? Many, many times. And how many times has Trump responded? None. Why? He fears bernie, with good reason. Trump often compliments Bernie and softens his criticisms of him. Why? He’s afraid.
What does that tell you? Sure, Trump has taken nameless swipes at socialism but not at Bernie directly.
Trump doesn’t fear the other Dem candidates, and he shouldn’t. They won’t win against him, and he knows it. #Bernie2020

Here is Trump responding to Bernie’s announcement. Trump is very subdued. And we both know why.
