A lot of things that people call "bribery" is really just ensuring that your preferred candidate gets in office. You couldn't give money directly to the candidate for personal use. Donations went to the campaign of the guy who already agreed with you. The FEC used to take a dim view of outright pay-for-service, even dressed up.
This is new. And now people need to decide how they feel about that. They get one chance to say "no, that's not how we do things." Even if the administration suffers a blow this November, if they hear that this is mostly acceptable to their base, it will be what every politician does from here on.
