The article talks about how he should pull out of the race in order to not damage his future career. Newt is 68 years old. I expect he believes this is his last hurrah, his last shot at "being somebody." If he doesn't get the nomination now, his in office career is effectively over.
That being the case, why wouldn't he continue to play out the campaign? There are months during which Romney could shoot himself in the foot, commit the unforgivable gaffe. It isn't likely, but it isn't impossible, either.
On the campaign trail Newt has said that Romney is not the candidate to choose if Republicans want to win in November. Perhaps he actually believes Romney will cannot win that election.
Romney losing leaves Newt in an "I told you so" position going forward. Maybe he even believes this will position him for the 2016 nomination, a long shot at age 72. Hat tip to Lucianne.com for the link.
