U.S. Sen. Dick Durbin said the 47 Republican senators sunk to “a new low” in sending an open letter to the leaders of Iran, warning any deal they make with Obama to halt development of a nuclear weapon might be revoked by the next president, or altered at any time by Congress.

“It’s virtually unprecedented,” Durbin said. “Here we are in the middle of delicate negotiations. We’re down to the last few days. We’re trying to reach a point with our allies where Iran is going to stop any development of a nuclear weapon, to put inspectors on the ground, and 47 Republican senators elbowed their way into the room and say ‘Don’t waste your time. We get the last word on this, and we’re not going for it.’ It really is irresponsible, as far as I’m concerned."

In fact, some opponents of DST aren’t against daylight saving time per se: They think it should be adopted as the year-round standard time. Because it basically already is.
