Presidential candidate Donald Trump has solidified his position as the front-runner in the Republican nomination race, by taking the state of Nevada. It's the billionaire's third consecutive victory, after winning New Hampshire and South Carolina. The final returns show he garnered nearly 46 percent of the vote, almost twice as much as his nearest challenger - Florida Senator Marco Rubio. Texas Senator Ted Cruz was third. The candidates now prepare for what may be a do-or-die "Super Tuesday" next week.
