We can infer that the meaning of the word "bright" in this context is "cheerful" because the speaker begins by expressing their wish of having a fine time (a good or quality time), and continues by making a peculiar and, perhaps dreamy, comparison (the mountains to the white elephants). Thus, when the speaker mentions the word "bright", he or she refers to something enjoyable, radiant with happiness, cheerful.
Politicians' views on subjects like military expenditure and affirmative action have always differed by gender. People think that women and men have different political views, which is what the term "gender gap" means.
