As an EEM, I would have no way of knowing whether or not John Kerry went to confession before appearing in the church, cameras rolling. That is one major drawback to entrusting the distribution of communion to an EEM. In a sense, they are as compromised as the priest. They march to his barking orders! (Excuse me for saying so, but just one more justification for restricting distribution of communion to a validly ordained priest. If he errs, it's his problem.)
It would require more than confession - it would require a public renunciation of the sin, in this case, a public declaration that he was no longer supporting the pro-abortion/pro-choice position.
Archbishop Burke made this clear in his notification last year - because one who has publicly and obstinately engaged in evil must renounce it publicly, in order to make it clear to all that one is no longer engaged in the evil.
