Hillary Clinton's Campaign in shambles?

So I read this article yesterday called "Hillary the unelectable" by Mark Goodman. (Article can be found here) He raises some interesting points. The media is buzzing about Barack Obama's gains in momentum throughout this election, and people keep jumping on the bandwagon everyday. Both Bill and Hillary have been slinging everything they can at Obama, and nothing works. (I think it was on CNN that I read a quote from Obama saying that Clinton has been throwing everything they can at him to see what sticks) Even though Hillary won't admit it, we all know she has been pushing Bill to be the more controversial one in her election, he's even been seen pulling the racial card. Heck, Bill even tried to lie to cover up the "sniper fire" incident in Bosnia (as stated in the article above).
Not to mention with all of this, we have seen much remodeling done in Clinton's campaign. People stepping down because of outrageous comments, people getting demoted, people getting moved around... it's like Clinton is unhappy with her own campaign, and these are supposed to be people that she trusts and knows well. If she gets elected, what are we to expect to happen to her cabinet? She obviously doesn't know her friends and colleagues as well as she thought she did. It will be like the Bush administration with shuffling, and people being forced to step down. I know I don't want to have to listen to that every night on the news.
As you can probably tell, I'm leaning more towards Obama at the moment. Do the things happening in Clinton's campaign worry you at all?
