I'm sure there are plenty of people who think it won't be raised, but are they sane? I don't know.
An alternative story to Fallow's is: http://blog.heritage.org/2011/07/28/the-truth-about-obamas-b...
Which shows that Obama is more to blame than Bush, which is different than what Fallow's used in his article. Situation is normal as each side is blaming the otherside.
I think if you look at the make up of congress when significant increases in deficits occurred, it might give a better indicator.
John Mauldin has a book called Endgame, which is worth reading through Interlibrary loan. It presents some interesting ideas.
But what it comes down to is that the US is acquiring debt faster than is recommended. It is possible to correct the issue, but not sure the political will is present to do so.
