http://www.euronews.net/ Republican candidates for America's presidential election made their last appeals to voters in the state of Iowa, ahead of Tuesday's first poll in the contest, known as the Iowa caucuses.
The vote will kick off a state-by-state contest to decide who will challenge President Obama in the election next November.
Former Massachusetts governor Mitt Romney is said to be the favourite at present along with Texas Consgressman Ron Paul.
