What does "carry so much baggage" mean?

May I ask a question on phrase?

Recently I read a news which had this phrase. It seems to me that the phrase doesn't relate to physical baggages and luggage...

Does it mean burden? I've checked up some online dictionaries (Yahoo!, Webster, Oxford, Cambridge) but cannot get an answer...

Is there an origin as well?
