That's not what will happen.
I guess it's easier for you divide the electorate between GC and TC, but in a democracy the real political division is left wing and right wing. You will remember that the TMT exterminated left-wing TCs during the troubles just because they rose above the ethnic and racist agendas of others.
What will actually happen is that if the TCs choose to participate in the democratic process and voted left wing or right wing instead of wasting their vote on an ethnic agenda, they will be the political king makers in Cyprus because the GC votes will cancel each other out.
Therefore any political party will be foolish to ignore the TCs, because their chances of re-election will be zero.
