Clinton, Trump pad leads with Arizona victories
Washington - Under a shadow of overseas violence, Donald Trump and Hillary Clinton padded their leads on Tuesday with victories in Arizona as the 2016 presidential contest turned into a clash over who could best deal with Islamic extremism.
Long lines and high interest marked primary elections across Arizona, Utah and Idaho that were largely an afterthought for much of the day as the world grappled with a new wave of bloody attacks in Europe. The Islamic State group claimed responsibility for a series of bombings in Brussels that left dozens dead and many more wounded.
Yet there was a frenzy of activity in Utah as voters lined up to caucus and the state Democratic Party's website crashed due to high traffic. In Arizona, voters waited two hours to cast primary ballots in some cases, while police were called to help with traffic control and at least one polling place ran out of ballots.
