Indiana voters cast their ballots in key US presidential primaries Tuesday, with Republican Donald Trump hoping to knock out his rivals and Hillary Clinton seeking to further cement her status as the Democrats' presumptive pick. The latest contest in the 2016 race for the White House is seen as a day of reckoning for the movement to "stop Trump" led by his closest rival Ted Cruz. "I don't think he's got the temperament to be president," Trump said of Cruz in an interview with Fox News after polls opened.
By Emily Flitter BEDFORD, Ind. (Reuters) - On a day when his U.S. presidential bid could suffer a mortal blow, Ted Cruz became embroiled in a name-calling contest on Tuesday with Republican front-runner Donald Trump whom he described as "a pathological liar" in one of the most bitter exchanges in the White House campaign. Cruz, Trump's main rival, has been counting on a win in Tuesday's Indiana primary to slow the New York billionaire's progress toward the nomination. Campaigning in Evansville, Indiana, Cruz sounded deeply frustrated by the bombastic real estate mogul.
