Trump is publicly leaning on Senator Tom Cotton to stop blocking permanent daylight saving time, a fight that is mostly bad news for anyone who likes early morning light.

• Trump posted a long demand that Arkansas voters call Cotton — and shared Cotton's personal cell number — to push the Sunshine Protection Act through the Senate.
• The bill already passed the House by a wide margin, but one senator can stall it, and Cotton is doing exactly that.
• Trump's argument leans on golfers, tennis players, hunters, and farmers wanting more afternoon sun, with a letter from the PGA Tour's CEO attached.
• Cotton's answer: permanent daylight saving has been tried and repealed before because winter sunrises get absurdly late, and kids would walk to school in the dark.
• Sleep researchers side with permanent standard time, and past attempts — in 1970s America, post-war Japan, and Russia — were all scrapped soon after.

Outlook: Cotton shows no sign of folding, so the bill likely stays stuck in the Senate despite the pressure campaign.
