A cycle is only a cycle if you don't step out of it.
And I will also say this, if your political "success" depends on lazy journalists grabbing your lazy messages from X and slap dashing lazy articles with X screenshots of what you "said", then you are not the politician you think you are.
And for the others, what you fear is not what actually will happen. Stepping away from X will not make you irrelevant. On the contrary, it will put you in the spotlight.
