I always find it incredibly odd that people want their politicians set in stone. That was in 2008, for example, and if we are to look at our current landscape and compare it to then, of course there will and SHOULD be massive differences. Leaders that are capable of admitting fault show their connection to the common person, and that they are capable of listening to the will of the people who put them in office. Someone with a rigid perspective and who believes they are unshakably right is pure poison.
