A phrase used to describe
a stark difference between two things. Similar to
day and night, except it implies an improvement of the situation rather than a
deterioration.
Democrat: "Wow, I'm so happy that Obama is
in the White House now. The difference in our country's leadership has been night and day."
Republican: "Actually it's been
day and night. George W. Bush was the man."
Independent: "You're both wrong. It's been night and night. Both parties are corrupt as hell."
Libertarian: "No, I'd say it's been more of
dusk and twilight."
Left-leaning moderate: "You're crazy. It's totally been dusk and dawn."
Normal person: "Seriously guys, shut up."
