If you could hop in a Wayback machine and go to 1971 - your approval rating by baby boomers would have been lower and for good reason.
Personally, I don't trust survey data - too easy to manipulate. Not nefarious intentions but too shallow a survey pool and questions that aren't layered to really get true feelings.
If you ask Qs like do you like Trump or not? People will say yes to support Republican "values" even when they dislike the man and wouldn't trust him to safely walk their dog. A "good survey" in my opinion would be at least 5000+ people, preferably 10K+.
