That's like listening to footballers/football managers interviews though. "It's always difficult coming to play against [insert any team name]". "We've been working hard in training all week and next week we'll work hard in training again".
When would a politician ever come out and say now's the perfect time for a bit of "party politics"? If a person has joined a political party, been elected to represent that party, risen to the rank of leader, it would be pretty weird if they didn't think that party was a vehicle for some sort of good. I just don't see how you can ever expect a politician to avoid painting their own party in a good light, and their political opponents less favourably. What would the alternative even look like?
