Good enough for what? Apologizing for doing something wrong doesn’t mean everybody else has to treat you like you didn’t do something wrong. Especially after you tried to lie about whether it was actually you. His 54-word boilerplate “apology” does not demonstrate that he understands why what he did was wrong or the harm that he caused. It does nothing to address or offset that harm. It doesn’t demonstrate remorse for the negative impacts of his actions, only remorse for those actions now having impacted him. It fails to offer a convincing plan that will ensure that his behaviour changes in the future.
So no, it’s not close to enough, actually. I don’t think he’s sorry for what he did. I think he’s sorry his attempted cover-up for what he did didn’t work. When he issues a real apology, one that demonstrates reflection, understanding, remorse, an act of reparation, and a clearly-planned intention to correct his behaviour, and when his behaviour has improved for long enough for the public he claims he wishes to serve to have real reason to believe it, then that’s enough. Until then, screw this guy.
