"I love it when politicians change their views on policies, if that view best represents the constituents that the politician represents."
If they actually change their views to better serve their constituency, ok. But most of the time they are just pretending to get reelected.
No. There are values and positions I hold that I would not want a politician to push policy against, even if a majority supported it.
I'm not sure I understand this question… Your quote started with the words "I love…" Are we supposed to agree that you love something?
If somebody told that to you, would you agree with their statement or disagree with it?
I would agree.
