Absolutely, the league title situation shouldn’t enter into the decisions a ref makes in a match, each incident should be judged on its own merits. If a player deserves a red card, he should get one, regardless of the team’s position in the league. You could argue that Clattenburg actually gave Tottenham an unfair advantage over Leicester by acting the way he did.
He did give them an unfair advantage undoubtedly. Just glad it didn't change anything. At least we won't ever see him back here again.
