All polls have had FF consistently on 16 - 18%, so nothing new in that regards.
FF will not start to rise until after the organisation has been reformed, and a lot is riding on next weekends Ard Fheis.
Also, if you think FF were bad wait until you see SF in government! Although on the other hand, if SF were to enter government tomorrow the party would be obliterated at a subsequent election.
Their last S&A poll was 20% in Dec for the times
Comparing apples with apples this represents 4% drop for FF
