It matters who has the most chance of winning.

If there are 10 competitors and they all have between 5-10% chance of winning you have 15%. Compared to a 15%/85% split.

When it comes to a company 15% isn't too bad as you have a long time to test and figure out whether you make it. It's never just about one exact moment.

With an election it can usually be summed to important event: the vote. So that's why it doesn't terrify me at all. There's enough evidence now and in previous elections to show me he's not going to win the election. If the situation were say closer to Gore/Bush or even Romney/Obama pre-vote polling numbers, then maybe I'd be scared.
