If the Regent thinks it's proper to lump the Monarchy options together to "juke the stats", then it's only fair to do it for the other viewpoint...
The clearest mandate to take from this referendum is that the status quo was soundly rejected.
In round one, just 23 people voted in favour of the status quo, while 62 voted for options of change. That's 86% of first preferences seeking a change from the way things are today. If we further look at those 62 ballots, only 4 of them selected the status quo option as their second choice. Going to the next round only 14 of 62 ranked status quo as their third preference.
Even when lumping the two monarchy options together you only get 42%, but it should be pointed out that those two options are completely incompatible with each other. Indeed, option 4 (for a wholly ceremonial Monarch) was the most preferred second choice to the voters who want an elected head of state as their first choice (22 of the 30).
The nation may be divided on what the future form of State should be, but it has spoken clearly in saying that the status quo must change.
