Republican candidate Mitt Romney's victory in the Nevada caucuses puts him in pole position for the Republican party nomination to challenge President Barack Obama.

Romney won by a big double-digit margin over former US House Speaker Newt Gingrich, Representative Ron Paul and former Senator Rick Santorum.  

Gingrich said he would continue to fight for the nomination.

But Romney should have the wind on his back for the rest of February. He’s favoured to win in upcoming contests in Colorado, Minnesota, Michigan and other states.
