He will have covered this story for fours running, and sees it has something that he has to get through. As a result his coverage is the barest minimalist coverage he thinks he can get away with. Thankful that the story is done and he can return to civilisation the following day he goes to sleep that evening in his hotel room.
The next day the alarm clock goes off and they are playing the same music, and telling the same news, a little odd. Shortly thereafter he comes to the realisation that it is indeed Groundhog Day, again. He goes to sleep that day hoping to wake "tomorrow" and that this was just a bad dream. He's not that lucky, it's Ground Hog day, again.
At first he seems to use the repeating day to his personal advantage and does whatever he wants knowing that there will be no consequences for his actions. This however becomes tiresome after a while, his next move is to use the day to improve himself.
This does present an interesting question, what would you do if you had to repeat today, over, and over, and over? It could very well drive someone insane.
