I wouldn’t consider a reach at all. You sound like a partisan hack.
We deserve to know all aspects of candidate’s past, McCain and Obama. Including Obama’s previous associations with Ayers, his pastor, etc. Both sides are spinning the stories to make it look as bad as possible.
McCain commented himself that it was “the lowest point in his professional career” and he admitted poor judgement. He took sizeable campaign contributions and Keating flew his whole family down to the Bahamas on multple occasions. He was the closest Senator to Keating in terms of personal relationship.
On the upside, he saw the errors in judgement and repented by launching a campaign finance reform initiative, eventually resulting in the McCain-Feingold Bill.
