Available for over a year

Donald Trump continued to dominate the Republican race for US president by causing further controversies in the first debate. The tycoon's refusal to rule out a third-party run damaged his chances, said former Republican strategist Ron Christie. "Americans are extraordinary loyal to their party of preference." Mr Trump "really lost an opportunity from a perspective of gaining credibility" to people who consider him as a reality talk show host, said Mr Christie.
