[mysql] MySQL compare now() (only date, not time) with a datetime field

I have a duedate column(datetime format) that specifies the due date of a ticket, now i need to get 'Due today' tickets base on the comparison between now() with duedate. i.e 2010-04-29 02:00 vs 2010-04-29 10:00 would return true in this matter.

Compare date only instead of date + time (NOW) with:

CURDATE()
