Our representatives aren’t being disingenuous.
The problem for northern states is the sun goes down too early. Right now, Minneapolis sun up at 7am, down at 4:54. Seattle 7, down 4:44, chicago 6:28 to 4:38.
https://www.timeanddate.com/sun/usa/minneapolis is one way to visualize (there's a graph at the bottom showing the dst/st change). A few days ago in the northern latitudes it was sun up at 7:50p, down at 6pm. Now it's an hour earlier. It's much nicer to push sundown an hour later.
