Is it true that you can't win an election by just one vote?

Thea Brodkin (Voter Service Chair) gives expert video advice on: If I don't vote in an election, is my registration invalidated?; Will my ballot be invalidated if I don't vote for every office?; Will my vote be counted if I don't register with a party? and more...

No, of course you can. Fifty percent plus one is a majority, and most elections are majority elections. Now there are some elections that require a two-thirds vote, like tax issues; certain elections have different percentages are needed to win. But most elections are a simple majority election. So of course one vote could make one big difference.
