If you define good idea as "that which causes leftist donors to give to the democrat party" then yes. They won't get paid anymore if they don't give their supporters what they want. It's like the little retarded girl they made the prophet of the environment, the in-authenticity coming off their carefully and poorly crafted speeches is painful, and it's obvious they're alot more interested in the money, power and prestige than the cause they hold a flag for.
It's also survival. Leftists take entire articles about why Trump will eat your baby too, and attack the author for not being sufficiently anti-Trump on micro-lack-of-aggressions here and there. Those were Daniel Greenfield's ideas mostly, another is most democrats are in a PTSD denial world where they can't accept it happened, and "impeach" translates loosely to "time machine" or "we can fix it" in their heads. This gives them that extra push to get out of bed in the morning.
If you simply look at people saying impeach as people saying "I can't live in this world", I have found it easier to reason.
