: When posting my last query I used the above term. Which lead me to wondering where it came from. Sounds like maybe a rowing term or something?? The word 'midstream' implies English origins to me.
I believe the original is something like "don't change horses midstream". A risky maneuver, not recommended even for experienced riders, if the stream is deep or fast-flowing. Extrapolated: stay with the "horse" you have. Frequently used in regard to elections, to politicians in office and other entrenched individuals.
