New twist in US Republican campaign as Jeb Bush puts the boot in

This US presidential election is seen as one of the most bizarre in modern times, with Republican frontrunner Donald Trump setting the tone. But now Jeb Bush is joining in by questioning another candidate’s height and the boots he wears.
