You should read his book written in 2011 “Time to get Tough”, before making such statement. What he said in his book, is exactly what he is saying now.
The fact that he’s been saying the same thing for 4 years doesn’t really mean much. Especially when you look at what he said before that. The guy spends a lot of time in front of cameras and writing books, he changes what he says a lot. Changes his party affiliation a lot too.
