There have been heated exchanges during the latest televised debate between the main US Republican presidential hopefuls. It was dominated by attacks on the front runner Donald Trump by his two biggest rivals. Senator Ted Cruz questioned Mr. Trump's rhetoric. “I understand the folks who're supporting Donald right now. You're angry. You're angry at Washington and uses angry rhetoric. But for forty years, Donald has been part of the corruption in Washington that you're angry about.” He also said Mr. Trump had a patchy record of support for previous Republican presidents. This was Donald Trump's response. “I support politicians. In 2008, I supported Hillary Clinton. I supported many other people by the way. And that was because of the fact that I'm in business. I did support very heavily Ronald Reagan. I also supported George Bush by the way.”Senator Marco Rubio questioned whether voters could trust what the tycoon said. Mr. Trump retorted by accusing Mr. Rubio of letting the electorate down by not voting enough in the senate.
