I have no question that he has the stomach to do whatever it is he determines to do.
I think the question is: does he have the gut instinct to determine what it is that conservatism demands him to do?
Bush, for example, went against elite opinion by trying every which way to reign in Fannie Mae and Freddie Mac, including in 2005 introducing legislation to strengthen regulation. This would have gone a long way toward helping to minimize the housing crash.
The Dems fought Bush's effort tooth and nail -- and so did Newt Gingrich, the man who took millions of taxpayer dollars in consulting fees from Freddie Mac.
I find that inexplicable and politically unforgivable.
It doesn't matter how much courage a person has if he isn't being courageous about doing the right (conservative) things.
Newt has been compared with Churchill, and Churchill was never a Tory. During the campaign of 1945, Churchill was curiouslly uneffective, His heart was not in it, because thought he despised socialism, he was in favor of the welfare state.
