I guess I do not see his relationship as a problem. He is operating in a system in which groups of people have hired lobbyists to represent their interests. The reality is, the average Joe doe not have access to the politicians to voice concerns ect, and that is why the system is what it is. So her having access does not bother me, at all. If you look at this man's record, he has bucked the party, bucked special interests, bucked popular opinion when he feels it is in the better interests of the country. And that record, stands for what it is.
As for this 'scandal". I believe that there was a rift within his advisors. I believe that there were firings and terminations that have resulted in this coming to light in a manner that is lacking in substance. It brings out the juiciness of the scandal without there being evidence of a scandal. I find it wrong and offensive, that the article sat, sat, was rewritten three times, sat again, and was published because there was an article being published about the rift it was causing in their paper. It was not published because it was newsworthy.
That said, like with Obama, if there is evidence of wrong doing and him using his political influence inappropriately, then I will be so disappointed.
