While I do not have a lot of time for Bertie Ahern, I don't think this is newsworthy. The post of Director of Elections is not a public post. He is free to hire whoever he likes. And if this man is an old friend, (as Mr. Ahern has consistently stated) it would be hypocritical to distance himself from the guy in the interest of PR.
In fact, on reflection, Mr. Ahern would go up slightly in my estimation for sticking with this friendship (of course, he would go up a lot more in my estimation if it was shown that he was sticking with a friend and that this was actually costing him votes, ....)
