The country's in such a mess, and if FG are not in government next time round (which is highly likely), inevitably the other party/parties will be just as unpopular. In my opinion, none of the parties have the ability or "expertise" to provoke change or effectively remedy the issues we're facing either.
Opinion polls, although not always to be relied on, do show that Fianna Fáil are the most supported party at the moment -
