I am fairly skeptical of the assertion that most Americans favor Standard time over DST.
My skepticism extends to the 2019 poll[1] that asked Americans if they "Supported Ending Daylight Savings Time", a Q that bundles Standard Time with ending clock shifts.
The Q to ask is "For year round time, would you prefer Standard Time or DST?" This would better allow us to consider what people at different latitudes want.
