Both trumpet policy that is based in fantasy and upon fallacy, and is completely incongruent with other of their policy. They are at best dishonest and more likely completely ignorant.
The only difference is one is a wildly successful narcissist who probably doesn't want to be president but, rather, wants to see if he can get elected president. The other is a rather unsuccessful loser who has never had a real job, but had the fortuitous fortune of being a the biggest dopey leftist at a time when Democrats were so lost they actually thought being a dopey leftist was a good idea.
