Cruz comes up trumps in Iowa

In Democratic race, Clinton in virtual tie with her rival Sanders

Ted Cruz, a fiery, conservative Texas senator loathed by his own party's leaders, swept to victory in Iowa's Republican caucuses, overcoming billionaire Donald Trump and Florida Senator Marco Rubio. Among Democrats, Vermont Senator Bernie Sanders rode a wave of voter enthusiasm to a virtual tie with Hillary Clinton, long considered her party's front-runner.

Cruz's victory in Monday's caucuses was a harsh blow to Trump, the supremely confident real estate mogul who has roiled the Republican field for months with controversial statements about women and minorities.
