U.S. President Barack Obama and Republican presidential candidate Mitt Romney are calling on voters to cast their ballots early with the election less than two weeks away.

In the U.S., voters in many states are allowed to cast absentee ballots or vote at election offices ahead of the election.

Obama, who has toured some eight states in just two days, urged voters to vote for him early during a speech he delivered in Tampa, Florida on Thursday.

Romney also called on supporters to vote early during a speech in Reno, Nevada.
