Earlier quoted context omitted.
If US states want to get rid of time switches they are free to go to year-round Standard Time (like Arizona).
You're saying the federal government granted blanket authorization to switch to the one? So the only reason states wait on authorization is merely obtusely insisting on the wrong choice? (In addition to being impotent.) The more I learn about this issue the more things I find to be angry about.
The special auth. from the Fed's is needed to switch to "permanent summer time" (and, possibly advocating for year round "summer time" gives the state politicians cover to do nothing, because "their hands are tied...").
