What does “toss-up” mean in American English?

When something is a toss-up, nobody knows which side will win. The phrase comes from tossing a coin — heads or tails, 50-50, no clear winner. In US politics, a “toss-up race” is an election so close that either party could win. But you can use it anywhere: “Shall we eat in or go out?” “It’s a toss-up.” One short phrase, many situations.

In the clip, a host talks about the upcoming US midterm elections and names Senate seats in Maine, Michigan, and Ohio. She calls them “the Cook Political Report toss-ups for the Senate” — seats where neither party has a safe lead. The phrase does real work here: it tells viewers these races are genuinely uncertain, not just slightly close. Outside politics, toss-up fits almost any equal choice. “Both job offers look good — it’s a toss-up.” “Coffee or tea this morning? Honestly, it’s a toss-up.” The literal sense — actually flipping a coin to decide something — still exists too. But the wider meaning, “too close to call,” is the more common one. You will hear it in news broadcasts, everyday conversation, and sports commentary.
