"Most of America doesn't live politics 24/7.

I have to agree with you on that point, but it does beg the question - so who is it that Trump is trying to influence with a claim that he is a stable genius, to focus on the most recent outpouring ?
A very large part of his base has probably never even considered that he could be anything other than stable. He's got them and they are not his problem. They are unlikely to be swayed by CNN spouting the words "stable genius " 24/7 because they don't watch it and they will vote for him and the GOP no matter what.
On the other side you have never Trumpers of every political affiliation and nothing he can say or do is going to get them onside, certainly not claims to be a stable genius. They will never vote for Trump; some are undoubtedly Republicans who may well jump ship in 2018 if the GOP continues to be tightly tied to Trump.
In between there are the undecideds. How you can be undecided at this time baffles me, but these are the votes that will probably sway the 2018 mid-terms and the 2020 election. Your take is that somehow they will be subliminally persuaded by Trump's statements to believe that in fact they should not worry about his state of mind - everything is fine.
I do not accept your premise, but even if I did, I would also have to require this group to disregard his day to day actions, his constant steam of unPresidential tweets, his ignorance of political and legal process and the avalanche of chaos that follows him around. I don't believe that Trump's tweets are persuasive enough to overcome that. If you do, fair enough.
Trump is a world class con-man. This is a skill, without a doubt, but it is not a skill set suitable for being President. As his term in office progresses I don't doubt that many will marvel at the sheer balls of the man, but I strongly suspect that even more will come to realize that having balls and nothing else is not enough to do the job he's been handed.
