Nope. His supporters like him because he gets away with things. They want to be him because they want power. They have little control over their daily lives and they think they deserve more, by any means necessary.
If he’s locked up it’s a downer. It makes him look weak. If you think jail will make Trump a martyr, you don’t understand why his supporters like him.
They want power. They want to be on top. When (not if) he’s put under house arrest, he will go down in popularity.
