I have been arguing this one for some time.
I actually think there are some very good reasons to doubt the polls:

That is not the only reason to doubt the polls, there are always the simple unrecognized variables (such as time of day, day of week, etc which can skew results) and the possibility of simply slanted questions, as well as misreporting polling subjects.
In any case, it would hardly be the first time polls would been completely wrong:
