Two parties, call them Andrew and Benjamin (the terms invented by the Right were "Left" and "Right"), representing opposite ends of the available spectrum of policies (draw a line between two points...).
Voters distribute themselves along this spectrum according to their own political opinions, with those preferring more of Andrew's policies positioned closer to Andrew's end of the spectrum and likewise for Benjamin. In the middle are a mass of voters who are pretty much ambivalent towards the two.
Now, say Andrew currently holds the majority. Benjamin wants to change this so moderates his policies a bit to have broader appeal - in other words, to claim a larger share of the political spectrum and snag voters who are currently on Andrew's side.
Of course Andrew does the same, and also moderates his policies.
Repeat ad nauseum.
Eventually both collide in the middle and there's really no difference between them any more.
Chances are that meanwhile there are new candidates appearing back out at the extremes who can restart the whole process again.
