Hanging by a thread

I found a very interesting article with a list of 90 democratic seats in trouble come the election in November.  I am always a sucker for articles like this because it is so hard to find any kind of national article on all of the seats in 'trouble'.  Unfortunately this is only about democrat seats in trouble at least the author took the time to say a couple of things why they thought the way they did.  I think the article likely over states the danger to some of the seats and definitely tries to play up that everyone is upset with the current administration.  I think these are unhelpful to the article but it is the world we live in...
