It is sad there is no other third or forth alternative, sadly the only party to create divide was UKIP which appeared to appeal to left and right voters .
I guess the Liberals could fill that void but folk just don't seem to respond to them ( I gave them my vote last time around )
I see voting sometimes as a tribal thing and both historical , bit like religion or race dislikes , whatever good the left or right party may do , some voters will never be accepting of either , and there is good and bad in both in my humble view.
