A: Conner has just announced his campaign for presidency.

B: That’s a big surprise. Given his track record, I don’t see any possibility of his winning.

Note: This is an informal saying that refers to the past record of the accomplishments and failures of a person, business, etc. This term probably comes from horse racing, where it signifies the best time a horse has ever achieved at a particular track or over a particular distance. However, some believe it alludes to track and field records. Its figurative use dates from the late 1940s.
