Heard Pakatan coordinated campaigns were lacking in Johor which is vital for Pakatan taking putrajaya. Only DAP pushing very hard. If things not improving for Pakatan on the reamaining days, Pakatan could be in for a disappointing outcome in Johor at least.
There is a great amount of in-fighting within the opposition ranks too. If any party wants to win, that would need to be managed. I think the parliamentary rules in Malaysia allows an elected Member of Parliament to defect their party and still retain the seat. Will stand corrected if someone could clarify.
