Some people seem to eat it up, but I'm increasingly suspicious that the majority of major websites' comment sections are generated by armies of astroturfers. The low(ering) approval ratings don't seem to come with any outspoken defectors in plain sight. They may be moderated away. RIP...a failure of the Democrats to work with the Republicans.
That's a fair point, and I certainly don't pretend to know whether it's an effective tactic. That said, I'm not 100% convinced that the approval rating polls are necessarily meaningful; I thunk it's entirely possible that plenty of folks will say they don't approve of Trump when asked directly by a pollster, but then will still defend Republican actions in general, as well as Trump when compared to anyone else.
