Trends have emerged in Guyana where political parties, principally the PNCR, sometimes define their responsibilities as relating to only those who they ‘represent’ or their ‘supporters’ or who ‘voted for them,’ even though, as Government or Opposition, they are expected to represent the interests of all Guyanese. But political polarization over the years has created an outlook so partisan in nature that political parties are tempted to look out for, or confine their responsibilities to, only those who voted for them. The PNCR, as the PPP generally does, should hold itself out as representing all Guyanese and its policies should be so explained, if it intends to acquire and retain broad appeal. With both parties adopting a national mandate, a division in either weakens its capacity to represent the interests of the Guyanese nation.
