Should There Be A Winner?

[SciFiBoy]

in an election if this is the result:

Did note vote: 54%
Party 1: 26%
Party 2: 14%
Party 3: 5%
Party 4: 1%


can any party claim to have a mandate to represent that constituency?

surely, if more dont vote, than vote for the winning party, democracy dictates, we nullify the result?
