front-runner

In politics, a front-runner is a leader in an electoral race. While the front-runner in athletic events is generally clear, a political front-runner, particularly in the presidential primary process, is less so as a potential nominee may lead in the polls, have the most name recognition, the most funds raised, or a combination of these. The front-runner is most often declared by the media who are following the race and is written about in a different style than his or her challengers.
